Nice! It’s working! Thank you so much!!
Where should I delete the “whitespace”? The error is occuring when posting, updating a post, opening the theme store and now even when i try to log in.
I deactivated all my plugins, but it still doesn’t work. When I try to load (for example) the theme store it says “An unexpected error occured. Something may be wrong with ww.wp.xz.cn or this servers configuration. If you continue to have problems please try the support forums.” Any clue, what that means?
