I have recently reinstalled Zenphoto on my webpage as the previous old version just quit working all together, but instead of going through a third party installer, I downloaded it direct from Zenphoto. However I can't get it to work. If I go into the website/zenphoto is brings up the message: The site is undergoing an upgrade. Please return later.
If I go into the website/zenphoto/zp-core/setup.php it gives me the message - A configuration error occurred. Please return later.

I asked my hosting provider and they thought the database had been setup correctly, but couldn't work out why it wasn't propagating properly. Do you have any other suggestions of where I can look for possible glitches?

Have managed to get it all working again with some set up help from my provider.
