I tried installing MobileJoomla! yesterday and got the "Incorrect usage of Mobile Joomla" while toying around with getting menu separators to work. I reversed this mistake, but now the main content container on all pages is cutting off text on the righthand side of content. I'm not entirely sure if it's related, but it doesn't seem like coincidence. The other person who intermittently manages the site partially uninstalled the extension, which I am currently re-installing to deal with this problem. Any suggestions? See the weirdness here.

Looks like an issue with CSS. I don't see how this would be related to Mobilejoomla.

Please use Firefox + Firebug to pin down the problematic CSS statement and related add-on and then trace this it to its plug-in. (my 3 seconds of debugging hint fpss-outer-container)
