Do you mean to disable all the extensions on the website?
If so, I just can't turn them all off all at once.
Is there a particular type of extensions that the issue could be related to, so that I could try turning only those off?
Is it possible it happened when I updated to the newest Guru version? If so, is there a way to revert to the previous version and find out if it is still working with that version?
FYI, I just created a new course, using a brand new teacher that I just registered. I am able to add lessons, but I cannot go back to edit them (same error message as for the ones mentioned before). I do not understand how this could be related to another extension.
Tks,
Serge
