I just found that my site was hacked, but the hacker just changed the index page, so I decided to download the gallery gallery again (the newest version, my previous gallery was an older version - no idea which - this might be a problem?), as I keep it only online. And I uploaded just the index.html file. The gallery now has its previous layout and everything, BUT there is a message:
Fatal error: Call to undefined function adminmessages() in /usr/export/www/vhosts/funnetwork/hosting/spcz/index.php on line 767
which won't let me see the main categories and stuff like that.
Can anybody help me, please?
Thanks in advance.
My gallery is here:

You can't just upgrade single files. You need to upgrade the entire gallery, doing as suggested in the docs, section "upgrading". That will not sanitize your gallery though from getting hacked - do exactly as suggested in http://forum.coppermine-gallery.net/index.php/topic,51927.0.html
