yep but i don’t have these plugins..
Ok, it will probably be a proces of elimination. Turn off all your plugins and activate one bye one.
Note: I am not sure what is happening here exactly, so you could wait for MichaelH [or anyone else] to advise you if you prefer. He is much more talented than I and may be able to suggest a far better solution.
I deactivate and try to reactivate now, it gives “fatal error” with “sidebar modules” SBM plugin….
Plus some post are regular categorized now, but the new one are “uncategorized” what a mystery…. I really don’t know what to do now.. return on a old wp version?!
