This is a major problem for many of us as we cannot use the buttons in the menu bar in version 2.5.1, and I think I may have found out why.

When you go to "inspect element" on one of the active buttons you get the webaddress, as you do with the button "Advanced Features". It looks like this:

*************************************************************************************************
<p class="tree_item leaf active_tree_node">

<a

href="http://www.online-ce.org/admin/settings.php?section=optionalsubsystems"

> ... </a>

</p>
************************************************************************************************

But when I click on an inactive button, there is no valid webaddress, such as with the button "Development"

***************************************************************************
<p

class="tree_item branch"><span tabindex="0"> ... </span>

</p>
*************************************************************************

Could this be the problem? Could it be that the button is not properly directed to the page it needs to be directed to?
