Admin works -- FRONT end doesn't show!

Okay, here's one.

My customer had a fight with his old hosting company, so I'm trying to move his whole site to a new server.

I CAN log into the admin -- it's reading the products in the db just fine, etc.

However -- when I try to go to the front page, I get a blank screen with this:

1065 Query was empty
in:
[]

I tried rewriting the files to make sure it wasn't a corrupted file. It's most likely (I hope) not a corrupted db, because it can read the admin side just fine.

ZC: 1.3.7.1
Server OS: Linux 2.6.19.2-grsec
PHP Version: 4.4.6 (Zend: 1.3.0)
Database: MySQL 5.0.41-log
HTTP Server: Apache

Any ideas/suggestions??

Sorry for the generic answer, but this is what I'd do:

Thanks for the information. By the time I got home yesterday, the customer had already had a problem with the customer service of THAT service provider too, and canceled his account with them. So now I'm in a holding pattern of waiting for him to decide what he wants to do. LOL

He still has a back-up site (through yet another provider) that's still up and running for now.

Make me SO glad I found the hosting provider I did! LOL I haven't had any trouble with mine. (Did I just jinx myself? LOL)
