I disabled the plugins, and activated the default thema. That helped a lot. Then I enabled the plugins again, that didn’t make a difference. So it must be the theme. It isn’t a very diffucult theme though… any ideas?

Nope, the host is just connected to this account. Already tried to disable the plugins, but unfortunately that didn’t work.
