I recently upgrade my website http://www.greekla.com from Active Forum v 3.0 to 3.6.5 running on DNN 3.2.2.  After the upgrade the forum link in my menu at the top of my site gets distored when selected.  The support team said it had something to do with the TabSelected that my skin is using and Active Forums is using.  I went through to try to find the issue but wasn't able to.  I am not a programmer so don't know where to look or what to change.  Any suggestions on what needs to be changed would be greatly appreciated.

Thanks
