My hoster Neobitti suddenly decided to sell all customers to another company and that company didn't want to keep customer which were more than "bulk host" customers. Thus I had to relatively quickly move everything somewhere else. In the end, I decided to move to Amazon Web Services because the prices are pretty good and the options are good for geeks.
Everything seems to work so far except the homepage buttons (again...) which I hopefully get fixed somewhen soon. If you find any other bugs, please let me know on facebook.
