Back to normal!
Over the weekend the site was going mad... and what i thought where solutions made it worse. After restoring the database most of the links in the navigation menu where lost, e.g. creating new things... administrating old ones. They where not only lost form the menu but i weren't able to access the pages with direct links ether..... after some hours fiddling around with everything, i created a whole new site and restored the database from a backup.
Some pictures are missing, i take the opportunity to upgrade to a new gallery module, please apologize.
