Hi there,
very strange thing is happening. Our users are reporting that they are not able to edit their profile. I tried to replicate this but did not find anything, suddenly after deleting my browser cache i am also no longer able to edit my profile.
Not sure whats going on here, because i did not make any changes to the site in two weeks. Last thing i did was related to this error -> https://stackideas.com/forums/profile-view-links-not-working-again <- which you resolved.
