Can't login to admin after moving to new domain

I just moved my zencart to a different domain on the same server. I followed all the steps in the tutorial, my cart looks good from the internet, but now I cant login to my admin area, it is saying I entered the wrong username or password.

I tried reading others posts and doing some of the suggestions but nothing has worked so I must be doing something wrong.

Could you please tell me exactly what to do. I sincerely appreciate your help.

Me,
Double check your settings in this file??

admin/ includes/ configure.php

I just checked the file settings and everything looks good.

Could there be another problem or do you think I'm overlooking something in the admin/ includes/ configure.php file?

Me,
Download this file and report back with the error please..

http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=860

ok, did what you said, this is exactly what the error log says:

[27-May-2009 12:04:56] PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: Cannot send session cache limiter - headers already sent (output started at /home/meesh/public_html/store/admin/includes/extra_configures/enable_error_logging.php:1) in /home/meesh/public_html/store/includes/functions/sessions.php on line 108

I don't understand any of this.
