Technical issues with editing profile

Please can you tell me why I am not allowed permission to edit my own profile, to add more details to my profile page? Every time I try to update my profile and save changes it says I do not have permission to do it! Why is this?

The About me section unfortunately can't be expanded beyond the one line text box.
I've been advised that the issue with logging out/logging in again to edit your profile is probably related to the recent cookie re-consenting changes. You shouldn't have to do this *again*, but let me know if you still have problems.
