I installed WordPress 3.5.1 last night and while I was publishing posts or saving changes etc I was taken to a blank screen with 'in' written in the top left corner. I'd go to claimthethrone.net/wp-admin and it would be back to normal until I made changes.
Now today I can't even login! I go to the longin page, enter my username and password and I'm taken to this 'in' blank page :-/
I tried the 'Trouble Logging In' support thread, and tried to emptying cache and cookies, disable plugins and revert back to twenty twelve theme, but it hasn't worked. Plus I've probably screwed everything by trying that stuff?!
MY THEMES: twenty eleven
MY PLUGINS: podpress, fix-rss-feed
I'd barely made any changes to my page but I don't want to re-upload all my content again just to have it fail like this again.
What should I do!
