Gallery has worked GREAT since 2003, now it fails?

I am not sure of my gallery version, but with this link, this should help you out: http://www.stickercutting.com/modules/gallery/view_album.php?set_albumName=digitalprint

My gallery has worked great since 2003, and has all of a sudden failed. I have tried to do everything in the window above, but the same error continues.

You can go through the setup as many times as you like, but the settings are never saved. I have chmodded the files, renamed files, tried to install, etc., all to no avail. No matter what, the settings do not save. Even on a new install, the settings are not saved and it will not let me continue.

I am now back to where I started, with nothing completed. Did my host change something on me and it messed up my PHP? This is the only thing I can think of. They are using Apache, as far as I know. My host is www.powweb.com

What a bummer!

Thanks for any and all help, I am about 4 hours deep into this issue, still with no resolution.

Feel free to go through the setup process if you like, to see the exact errors.

Note: I have contacted my host to see their side of things, and I touched nothing on the server prior to this failure.

I see no error either. Note that whenever you go through the setup, and it gives you the final link, you are linked back to the original "need to configure" screen and not the "Your new gallery" screen. Even IF I chmod them, that "need to configure" screen never disappears. Its like the settings aren't being saved when going through the gallery setup?

What could it be?

000 setup did it! But why didn't "0" do it?

After HOURS of messing with it, that was the fix? Wow........

Thank you so much.
