I have just found a bug preventing css to be loaded on sites like yours (where there is a redirection). I have uploaded a modified version so please, sldev, download and install it and tell me if it works.
In your site the Joomla notification bar doesn't work when you're in Securitycheck Pro menus. This is caused by the "System - Web357 Framework" plugin (after uninstalling it everything works fine). No idea what this plugin does.
I have been following this thread and thus, as advised, downloaded the SP updates from the SP website, and installed. Similar to this discussion, I can no longer use the Joomla menu to exit SP or anything else including logging out of the back end. Clearing browser cache or restarted computer does not help. Also, clearing Joomla cache via a different browser didn't fix. Please help.
As this is not the first case I'm going to think how to solve this issue. Can you download and install 3.1.4 version meanwhile?
Edited: You can also get the normal behavior overwritting the url to delete the "com_securitycheckpro" part (i.e /administrator/index.php?option=com_securitycheckpro should become /administrator).
