database problem after uploading the site to host

[Dolgion Chuluunbaatar]

Hello,

I made a website using croogo which works fine on localhost,
but after I put it up on the client's host, there came a problem which
I can only imagine to be something wrong with the database connection.

The database name, username and password and host are all correct as
far as I know.

If you would be so kind as to take a look, here is the address:
www.singmed.mn

It's a bunch of error messages, but I don't see where the actual cause
might be.
Any ideas?

what version of Croogo are you using?  

Have you got other sites working with databases on this server?
