[Solved]: Fatal error

[Charlene184]

Hey,

I have upgraded my sites to 1.4.17 yesterday, and today I apply the patch for 1.4.18, but here's what says my gallery:
Fatal error :

http://www.gaelfan.net/gallery/

It happend to another site of mine:

http://www.swcmuse.com/gallery/

Did I do something wrong ?

Thank you for your time.

Enable debug mode and see what the error is.

Can I enable the debug mode whithout access to the gallery ? I cannot access anything.

Ok so here's more, apparently when I do not access the page with my login and password (I've tried that on IE), it works but when I do, it says fatal error
