Today my admin panel acts weird. I don't see real problems until I want to write a new post. There the button "insert media" doesn't word. Sometimes the button "publish" is missing". When I want to link a word to an url, the moment I click on the specifici button it shuts my post. All the style buttons disappeared from the bar when I'm on the text view. When I want to add a featured image, the lightbox page opens but the look of the page is like the old one from a previous version of WP.
Well, I deleted few plugins yesterday that were already inactive. And a uploaded WP3 Total Cache, that I immediately deleted today thinking it was the problem. I thoroughly erased all trace of WP3 Total Cache everywhere (as it is explained on numerous website), to be sure that this plugin wasn't interfering. But nothing has changed.
So basically I deactivated one by one all my plugins and nothing changed neither.
I also reuploaded and reinstalled the last verison of WP, without any changes.
Is it possible to simply reset my admin panel WITHOUT affecting my posts, images,... (everything that a visitor has acces to) ? So it could maybe rewrite parts of code that seem broken or whatever ?
Thank you for your help !
