Second problem

Submenu of ARI Ext Menu, when first time , submenu shows ok, but when you click on the some submenu item and website loading, after this submenu not show corectly. When I clear cash , again submenu look fine, but after this not shown corectly.

Hello,

The same javascript code (not only for "ARI Ext Menu") is included twice. You can see it if open HTML source of the page. It seems this is a problem with Joomla! cache.
