@ eyema, Please confirm, so Αndré can help further, if possible.
1) If you try:
http://ultimate-tlc.flirtatious.org/gallery/update.php?theme=curveThen:
You are NOT logged in AND you are in the Curve theme.
2) You try to log in from the link on the update page or this one:
http://ultimate-tlc.flirtatious.org/gallery/login.php?theme=curveThen:
This error message -

AND there is only a blank page.
Please confirm and also reply if you or your host can edit php files.
Please also note that automatic installations and updates are not normally supported, because of the types of trouble you are now seeing.

@ Αndré,
If somehow the user has logged out and broken the gallery during a failed upgrade, could update.php be slightly modified so that an unlogged admin could run it? Perhaps even under a different name (ex. xxupdate.php) before it is replaced with a clean copy?
