Im using templete 00042. Everything was nice until you click About Us,Shipping & Returns, Privacy Notice and Conditions of Use. It mess up the navigation. Also if go to forum and sitemap, there no left navigation. Here are my site : http://www.mohadcollections.com
topic pages now use 2 column layout. Please download the theme again. Regarding sitemap and forums they use one column layout and therefore the left navigation is not displayed.
