So ive been trying some new themes on my website, then it started getting wierd when in theme options it didn't change logos or anything. So i left it there for a few hours, when i came back, the page was on previous theme again and when clicked on a category or page then there was another theme again, so i logged in deleted all themes tried one, looked okay, but then couldnt change anything in theme options, cos it just wouldn't change. Now that i logged out of wp-admin, the page had no layout at all :/ ( http://www.aslowcooker.com ). Some help would be greatly appreciated, thanks!
now it even shows old logo there that i used few days ago
