Help - Fatal error: Call to undefined function: pageheader()

[hannah]

I'm pretty basic on my knowledge of Coppermine and everything with my gallery was going fine then suddenly, I must have done something (God knows what and know when I try to access my gallery I get this:-

http://www.erin-daniels.co.uk/pictures/login.php

Fatal error: Call to undefined function: pageheader() in /home/virtual/site1/fst/var/www/html/pictures/login.php on line 72

I don't know what to do, my other site gallery is running fine, I think I accidently uploaded a template.html or theme.php from another gallery I have ...

ETA: Okay I think I've posted this in the worng place, pretty sure my version is an older version

you have cpg1.3.3, so I moved your posting to the board that corresponds to your version. Use this link: http://www.erin-daniels.co.uk/pictures/login.php?theme=classic to be able to log in, go to config and fix the broken theme.
Upgrade to cpg1.3.5 at least asap!
