 * YEH!
 * I got this same problem, but it was just randomly started after i played around
   with the my themes index.php file. It is definitely something to do with my theme,
   but I don’t know where i went wrong.
 * I restored my back up of the file, still no luck.
 * This is a real pain.. can anyone help?
 * Thanks
    Nathan
