Hello Malte,

So sorry for the delay in getting back to you. We must have missed your post. Actually all I fixed was replace a missing file

JOOMLA/media/foundry/2.1/scripts/responsive.js

Which should have work but seems like it didn't. I actually couldn't test it out because I can't login to your site frontend. Is the login credentials not correct? I tried again to login this time to no avail. Please advice.

Thanks!
