cannot log into admin panel after moving to new host

[tubanus]

Hi!

 

I moved my oscommerce store to a new host and reconfigured both configure.php files.

The store loads and operates ok now.

My problem is that when I'm trying to log into the admin panel (e.g. www.mystore.com/admin)

I get a prompt to enter the user name & password.

After I submit the required info I get the error bellow.

 

The server encountered an internal error or misconfiguration and was unable to complete your request.

 

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

 

More information about this error may be available in the server error log.

 

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8g DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at brandzboutique.com Port 80

 

Can anyone help me to figure out what the problem might be and and how to resolve it?

 

Thanks for your time and help!
