It was happening every time I would change the configuration screen.
I have since tried switching to a different hosting company and everything now seems to be working fine.
On a side topic, do you have any suggestions for managing user accounts between the various sections of the website? In other words, I use your Photo Gallery script, i'm using phpBB, and plan on using one or two others. They all allow user registration, but does the user just have to register separately on each one?
Thanks for the help.
Tim.
