I was doing a post this morning and everything was fine... Then I wanted write another one this afternoon and when ever I tried to get into the back end I would either get a 500 error or a blank page. I think it is my WP install as I still get the front end just fine. Any cluse what to check?
I deleted any plugins which I updated in the last two days.
I re-installed WordPress 3.2.1. used the same database and everything was fine. then I plopped in my old wp-content folder and the problem is back. I am using K2 from SVN I think it is 1.5.1.
Any pointers appreciated.
