When editing teacher ,admins or course creators click on "Turn editing on" button, the page is displayed containing only header and footer. IE shows the following JS error:
Error: Invalid argument
The problem does not appear in IE when:
- using another course format, such as weekly format (with AJAX enabled in user's profile)
- disabling AJAX in user's profile
When using FireFox, the problem does not appear whichever course format you select.
If needed, I can provide URL and credentials to login and test the problem.
