Cannot Edit Page

[davidh1]

I have been back and forth with Canvas support all day today and I just wondered if anyone else has experienced the issue I'm having. I have a particular course shell I have been using as my "base" to export content to my other course shells this summer. One page (just one of the nearly 40 or so) is somehow locked and can't be edited or deleted. I can go into "Edit" mode and tinker, but when I click "Save", nothing happens. It refuses to save. It looks like any other page in terms of settings. If I "Duplicate" the page to try to edit a copy, the duplicate is also locked--can neither be edited nor deleted. If the page is imported into another shell, the problem travels with it.

I can, however (in html mode) copy all the html, create a new page, and edit and save that. I can also use the incognito mode of the browser and edit and delete that way. Thinking it was a cookie/cache issue, I cleared all browsing data (from all time). Problem still there. It is totally strange and I have no idea.

Hello!  I think I'm understanding your workflow to edit or delete that page, but it sure does sound quite strange that you are unable to edit or delete it from your course.  When I looked at the screen shot that you included with your posting, the only thing different I could see was that the page was last edited by McKenna Merrill.  I don't know why that would have anything to do with you not being able to edit or delete the page, though.  Assuming that you and McKenna are both enrolled in your course with the "Teacher" role, I would think that you'd be able to edit or delete that page.  Have you checked with McKenna to see if she is able to edit or delete the page instead of you?  If she is not enrolled in your course, can you enroll her?  Or, have you talked with your school's local Canvas administrator or someone from your school's Online Learning/eLearning department to see if they are able to edit or delete that page from your course?  Just trying to think of some other options for you a this point.

Please keep us posted on this one in case you are able to edit or delete that page from your course...thanks!  Take care, stay safe, and be well.

So this took a while to figure out and I am not sure I understand it all just yet, though the case I opened has been closed I think.

The culprit was my ad-blocking browser extension, which is the same in both Firefox and Chrome, but is is disabled in incognito mode and not used in Edge (because I never use Edge). I confirmed it as the problem by toggling it on and off while I tinkered with the page I couldn't edit.

What I still don’t understand is why that one page only (and if I duplicate it) is the only page affected by that extension. There is nothing special about the page and I built it in Canvas just like my other pages and have been importing and editing it for some years since I first created it. The problem is not in the html because I can copy the html to a new blank page and don’t have any problems. The extension is normally on all the time and I can edit other pages just fine. I just can’t imagine what metadata is stuck to just that page that is interacting with the extension.

It could be just a mystery and I’ll have to move on. In any case, if others have this experience, look to your browser extensions first.

This has happened to the same teacher at my school twice now. (several years apart!) So I found your post, and then looked in his extensions. The only chrome extension he had that he could turn off was screencastify. So we toggled that one off, then cleared cache and cookies. And it resolved the issue! Not sure which variable fixed it, but thank you for the suggestion.
