We have another problem with just 1 (!) Menu-Item.
If you look at http://90minuten.at/90minuten2013 you can see the menu-item "Tagebuch". If you click on a sub-menu item, f.e. YouTube&Co the alias-url is: http://90minuten.at/90minuten2013/index ... /youtubeco
But if you click on the first article "Was für ein schönes (Eigen)Tor [Video]" you get this url: http://90minuten.at/90minuten2013/index ... ntor-video
So /tage-buch is missing. This happens with all articles in the sub-menus - just of this one menu-item. All others are correct. The problem is, that the modules in the sidebar (on the right) are not shown correctly of the wrong alias-url.
please can you give us a hint. thx!
