A thing I noticed that seems to cause some trouble are the .htaccess files I recently added to ZenMagick.

Intention is to protect direct access to ZenMagick code, while allowing the webserver to serve the theme files as required.

While this works on my test system and a few other sites, it seems to be broken for some. The effect is that CSS, JavaScript and images are not displayed at all. So all you will see is the unstyled page.

Deleting the .htaccess files in both zenmagick and zenmagick/themes should do the trick for now …
