I have been running WP 3.1.4. for a long time (can't upgrade due to hosting issue and a too old version of PHP). I must mention that I also am the creator and the only administrator of my WP.
Everything was going fine, but yesterday I made some changes, including the installation of 2 plugins, I wrote and edited article, etc.
And all of sudden, I can't do anything anymore ! I an click everywhere, and edit posts, but when I click "update" it says "Post edited successfully" but the changes do not appear !! The same goes for plugins : I click "deactivate" and it says "plugin deactivated" but the plugin is still activated !
This was driving me crazy so I manually deleted the 2 plugin files directly from FTP. Now they don't appear on the list but I get 2 errors ("cannot load plugin X : file not found"). This has not fixed my admin rights issue.
And when I want to Add a post, after clicking "publish for review" it just says "You are not allowed to edit this post."
I'm really lost, any help would be much appreciated,
