I actually re-uploaded my wp-includes folder and this resolved the problem.
I would agree with that, although the system was rather stable just a few days ago.
Should I consider re-installing wp 2.2.1? How exactly would I go about doing that?
I’m quite sure I haven’t edited anything in my /wp-includes folder and I’m already using the latest version of WP (2.2.1).
Should I try to re-load just the wp-includes directory?
