Text (.txt) Files in Sail

It is non possible to download text files (.txt) that have been added to Canvas sites; it is only possible to view a text file in the document previewer. Other standard file types like .doc, .docx, .pdf, .ppt, and .pptx can be downloaded from Canvas by clicking on a blue file link, just text files cannot be downloaded. For this reason, we do not recommend calculation text files to Canvas.

Periods (.) in "Restrict File Upload" List

Canvas won't let students submit file-upload online assignments if at that place is a catamenia (.) for an extension in the list of accepted file-types in the "Restrict File Upload" field. To stop this from happening, you must list files extensions without periods–doc, docx, pdf, etc. and not .doc, .docx, and .pdf.

Mime Blazon Issue in Firefox

There is Firefox-specific problems that can affect mime types for files. Older versions of Firefox can sometimes produce a mime-type error when uploading files to a website. When this happens for files uploaded to Sail, the file does not return correctly in the Sail previewer because the browser interprets it equally another file type; consequently, users either see  a string of code in the previewer or practice non meet the magnifying-drinking glass icon for previewing the file at all. Fortunately, this problems does not touch on users' ability to download files, just the ability to preview them, then anyone with access to a file in a Canvas site can download it past clicking on the file link even when the file preview is not working.

To ready this issue, yous tin practice the following:

1. Check to encounter that you are using a supported browser version. Whether you are using Firefox or another type of browser, please note that you should e'er apply a version of a browser that Canvass supports to avoid issues affecting older versions. Delight consult this list to see the browser versions Canvas currently supports:

Lost SpeedGrader Comments in Firefox

Nosotros accept learned about a new Firefox bug affecting SpeedGrader. When a Teacher, TA, or Grader uses the margin commenting feature for annotations in SpeedGrader with Firefox, they must click outside of the comment bubble on some other area of the document in order for the comment to exist saved. This has led to several cases where terminal comments are not being saved when the user navigates to the side by side pupil submission.

We recommend the following workaround for this upshot:

  • Utilize a supported version of Google Chrome or Safari instead of Firefox.
  • If you must apply Firefox with SpeedGrader, make sure to click out of the comment bubble onto another expanse of the screen when calculation your last annotate on a newspaper to ensure that it is being saved before navigating to the next student submission.

Also, please note that if you leave SpeedGrader open for a submission for a long time, you can also lose comments, even when working in supported browsers. While it might seem that this behavior is the same every bit the Firefox bug, please be bodacious that information technology isn't. Rather, it is the intended behavior of SpeedGrader when it has been open for a submission for an extended period of time.

Timeout Problems in SpeedGrader

SpeedGrader has a session timeout of 60 minutes. When a Teacher, TA, or Grader opens a document in SpeedGrader, Canvas will save all annotations for the next 60 minutes. After l minutes take passed a pop-up warning appears with instructions on how to restart your session to ensure boosted edits are saved.

SpeedGrader timeout messageDeclining to restart your session may result in lost annotations so we recommend adhering to the warning to ensure all feedback is saved.

Video Comment in Peer Review Marked "Incomplete"

Video comments submitted for a peer review are marked "incomplete" if they don't have accompanying text. To avoid this outcome, students should add text to their video-comment submission for peer reviews (eastward.g., "This is my submission").

TIFF Files Not Supported in Canvas

Sheet does not support TIFF files. For this reason, it is recommended that JPEG and PNG file types exist used in Canvass, every bit well-nigh browsers (Firefox, Chrome, Safari, IE, etc.) and Canvas support these file types.

Grading History Non Displaying All Grade Changes

The Canvas grading history for a pupil'south assignment form only shows the two about recent form changes in the terminal 24-hour period. Whatsoever additional changes made in this catamenia are not saved.

Tin't Message Students in "Concluded" Courses in Canvas

Red X over

Although the messaging choice for "Concluded" courses (meaning, courses from past terms that exist in a read-simply country) appears in the Canvas message-class, it isn't possible to transport letters to students in "Concluded" courses because these courses are no longer active, and students tin only access them in a read-but state. If you lot intend to stay in-affect with students from a class later the term ends, we recommend asking if they would like to commutation email addresses.

Teachers and TAs in "Concluded" courses tin can message one another using the "Concluded" messaging pick.

No E-mail Notifications for Courses in Hereafter Terms, But Push Notifications

Users practice non receive email notifications for deportment taken in courses in future terms. For instance, if y'all are a pupil in a course that is set up in Canvass for Fall 2020, and it is currently Summer 2020, you will not receive electronic mail notifications if your instructor takes an activity (due east.thou., creates an assignment). This issue occurs even for courses that are currently active but are technically associated with a future term (eastward.g., a Fall 2020 grade that actually starts in Summer 2020). Users do receive push notifications for these type of actions, yet. To learn more almost button notifications, please see "Set up Push Notifications"on this page (teacher data and student information). Our vendor is working on a solution for this issue, and whatsoever updates on it will be posted here.

No Quiz Statistics for Classic Quizzes with More than than 100 Questions or i,000 Attempts

Quiz statistics aren't available for Classic Quizzes with more than 100 questions or 1,000 attempts (i.e., more than than 1,000 quiz submissions from students for a single quiz). When you click on the Quiz Statistics link for a quiz that exceeds these maximum values for questions or attempts, the following message appears:

" data-image-caption="" data-medium-file="https://i0.wp.com/infocanvas.upenn.edu/wp-content/uploads/2016/08/sadpanda.png?fit=300%2C158&ssl=1" data-large-file="https://i0.wp.com/infocanvas.upenn.edu/wp-content/uploads/2016/08/sadpanda.png?fit=660%2C348&ssl=1" loading="lazy" width="660" height="348" class="alignnone size-full wp-image-3919" src="https://penncanvas.files.wordpress.com/2015/03/sadpanda.png?w=558&resize=660%2C348" alt="Cartoon panda crying and the message, " data-recalc-dims="1" data-lazy-src="https://penncanvas.files.wordpress.com/2015/03/sadpanda.png?w=558&is-pending-load=1#038;resize=660%2C348" srcset="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7">

Please consult the "Canvass Quiz Particular Analysis" document for more than information on the benefits and limitations of Sheet quiz statistics.

Equally a workaround, you lot can view quiz statistics by downloading the CSV files in the Student Analysis and Item Analysis links. You can so upload the file to Excel, Google Sheets, or some other spreadsheet and view the data in a much more than convenient format.

"Session Expired" Message When Viewing a Public Sail Site

A "session expired" message and a log-in prompt appear after several minutes of viewing the public version of a Sheet site either for users whose login information has been saved in Canvas from a prior session or for users who are logged into Sail in another browser window.

There are two possible solutions for this upshot:

i. Log out of Sheet and clear your browser's cache before accessing the public version of a Sail site. Here are instructions for how to articulate your browser's cache:

Clearing your cache on a PC

Immigration your cache on a Mac

2. Apply Google Chrome's "Incognito" mode if you want to remain logged into Sheet while viewing the public version of a Canvas site (more than information on Google Chrome'southward "Incognito" way).

Since this outcome only affects users who have access to a Canvas case, anyone outside the University of Pennsylvania who is not associated with a Canvas instance should not experience this issue. If a public version of a Canvas site is accessed past someone at another institution that has a Canvas case, they should follow either of the above suggestions to avoid seeing the time-out message and log-in prompt.

Points Display for Ungraded Surveys in Modules

Users have reported experiencing an intermittent issue affecting ungraded surveys added to modules. When this issue occurs, a point-value (e.g., "ane pts") displays in the module listing for an ungraded survey that has been added to a module. Our vendor has confirmed that this issue but affects how ungraded surveys brandish in modules and has verified that ungraded surveys that this consequence affects do not count toward the full form class. Our vendor'south engineers are working on a resolution for this result, and an update will be posted to this "Known Problems" entry when the issue is resolved.

50-User Limit for Collaborations

A maximum of 50 users tin exist added to a Collaborations Google Medico in Canvas. If at that place are more than 50 users enrolled in the form site, the Collaborations tool volition display simply the first 50 users alphabetically.

Hanging Indentations in DocViewer

In that location is an extra carriage return to the formatting for hanging indentations for documents displayed in the DocViewer that utilise unsupported fonts. This misformatting only affects how a certificate displays in the DocViwer and does non bear upon the file itself; when downloaded, the file displays the right formatting. Our vendor is working on a set for this issue, and an update will be posted to this "Known Problems" entry when it is resolved.

Gradebook-Consign Name-Sorting Issue

When you export the Canvass gradebook, sort the export past any cavalcade other than the "Student" column (for example: the "Concluding Score" column), and the re-sort the export past the "Pupil" cavalcade, the second sort re-orders the rows alphabetically by students' commencement names instead of by their terminal names. When a gradebook is exported, the file is sorted alphabetically by last name, so a re-sort of the "Educatee" column afterwards another column has been sorted does not restore the file to the original sorting social club. Our vendor is currently working on a solution for this issue. An update volition exist posted to this "Known Issues" entry when a solution has been implemented.

Mail service Final Grades for Muted Moderated Assignments before Unmuting

If a moderated assignment has been unmuted before a moderator posts final grades for the assignment, Canvas generates a notification that the consignment has been unmuted, but the grades and feedback on the assignment are even so unavailable to students considering the final grades have not be posted. For this reason, it is recommended that final grades for muted moderated assignments be posted before they are unmuted so that the notifications students receive near the assignment existence unmuted will accurately reflect the availability of the assignment's grades and feedback.

"i" Grapheme Not Displaying in Document Previews (Chrome 64)

If a box icon appears in place of an "i" grapheme when previewing a document in Canvas through Chrome 64, then Chrome 64 does not support this character in the font being used. Our vendor has confirmed that this issue should be resolved in a future Chrome release, but, until then, if yous encounter this issue, the following workarounds are recommended:

    • Download the certificate.
    • Preview the certificate  in Sail using a supported version of any browser other than Chrome 64. Please consult this list of browser versions that Canvas supports.

Some Special Characters Count as Words in the Rich Content Editor

`  ~ $ ^ = + > <

If you lot are an teacher or TA, it is recommended that y'all take this brake into consideration if you are asking students to follow a discussion-count limit. If students will need to employ these symbols, please factor the approximately number of instances a student might need to employ these symbols for the post-obit types of activities:

  • Text-entry consignment submissions
  • Word posts
  • Essay questions for Sail quizzes
  • Pages that students can edit

If you are a student, please take this restriction into consideration if yous have been given a word-count limit for:

  • Text-entry assignment submissions
  • Discussion posts

"Consign Failure" for Duplicate File Names

When a Canvas site contains files with the same name, an "consign failure" occurs for course content exports. To set up this result, a Instructor, TA, or Designer will need to delete duplicate files, or, for different files with the same name, they volition demand to rename all files except one.
