D2L Login: clearing cache

UWM students, instructors, and staff using ePanther accounts should go to the D2L landing page at http://D2L.uwm.edu and choose the [UWM ePanther] login path. 

If you reach the D2L Special Access Account Login page instead, you must close that page, and then clear your browser's cache (directions are available at: https://kb.wisc.edu/helpdesk/page.php?id=12384).

If you are a student, you will want to contact the UWM Help Desk at 414-229-4040 or go to GetTechHelp.uwm.edu if you have any further difficulties accessing D2L.

Clearing Browser Cache

Problem: After deleting an item from "Content" and "Course Files" when I click on the new file, the old document still appears.

Solution: Clear your browser cache. The browser stores files in the cache and, in addition to fixing the above problem, clearing the cache can improve browser performance. Below are directions on how to clear browser cache for IE, Mozilla Firefox, Google Chrome and Safari.


Internet Explorer 9.0
From the safety icon in the top right of the browser window, select "Internet Options"
Under "Browsing History," check "Temporary Internet Files" in the "Delete Browsing History" window
Click Delete
Click OK

Firefox 3.5 for Windows
Select "Tools" from the menu bar
Select "Clear Recent History"
Select everything from "time range to clear"
Click on the down arrow next to "Details"
Check the box "Cache"
Click "Clear Now"
Click OK

Firefox 3.5 for Macintosh
Select "Tools" from the menu bar
Select "Clear Recent History"
Select everything from "time range to clear"
Click on the down arrow next to "Details"
Check the box "Cache"
Click "Clear Now"
Click OK

Safari 5.0 for Windows
Click "Settings"
Select "Reset Safari"
Check the box "Empty the Cache"

Safari 5.0 for Macintosh
Click the Safari menu
Select "Reset Safari"
Check the box "Empty the Cache"
Click Reset

"Stack Overflow" Errors in Internet Explorer

Internet Explorer users may see "stack overflow at line: 0" errors in various areas of D2L.


These errors related to the use of Internet Explorer browser, and are not actually D2L errors.


You should be able to click through them, but to avoid the errors altogether, we recommend either:

• clearing your browser's cache, then accessing D2L directly at https://uwm.courses.wisconsin.edu rather than through the UWM Homepage 

OR

• switching to Firefox

NOTE:  Some users prefer Internet Explorer because they are not able to right-click to cut and paste in D2L when using Firefox.  However, keyboard shortcuts *will* allow you to cut and paste equally well in Firefox.  Here's how:

• To cut: hold down the [Ctrl] key and then the letter [x]

• To copy: hold down the [Ctrl] key and then the letter [c]

• To paste: hold down the [Ctrl] key and then the letter [v]

Two Unicode Characters Can Disrupt Functions in D2L for Non-IE Browsers

Two Unicode Characters Can Disrupt Functions in D2L for Non-IE Browsers

Two Unicode characters, the line separator and paragraph separator characters (U+2028 and U+2029), when used in the HTML editor, can disrupt a variety of functions on the page when viewed with browsers other than Internet Explorer. There are two documented examples of this. (1) If the characters appear on a Content page, the content is not visible to Firefox, Safari, Chrome, or other non-IE browsers. The navigation functions through the Table of Contents sidebar may also be disrupted. The content can be viewed if the window is undocked. (2) If used in Quiz questions, you can preview the questions with the unicode character and you can see the question text and choices when you are in the Add/Edit view, but when you attempt to edit the quiz you cannot; none of the buttons except Cancel work

If you encounter a situation where there is user-generated HTML content on a page that works with IE, but not with other browsers, please inform the Learning Technology Center. We will complete a Problem Reporting Form and ask our host Utility to contact the vendor to look for the offending characters.
