Np :)
From what I can see, the notification it looking for a module that could have possibly have been un-installed or deactivated.
To get around this you could modify the code at these lines:
le="color: #000000"><?php $module =& $module_handler->get($modid); $modules[$modid] = array ('id'=>$modid, 'name'=>$module->getVar('name'), 'categories'=>array());
To This:
le="color: #000000"><?php $module = &$module_handler->get( $modid ); if ( !is_object( $module ) ) { continue; } $modules[$modid] = array ( 'id' => $modid, 'name' => $module->getVar( 'name' ), 'categories' => array() );
Be aware, I am not 100% that this will not have any side effects, but it should kill the error and allow you get back into that page.
