Hi Gang!

Everything was working just fine till today when I discovered that every page in my zencart gives a blank page (www.gabkits.com)
I found these errors in the php error logs:

Code:
[19-Feb-2014 09:51:23 America/Denver] PHP Deprecated: Function ereg() is deprecated in /home2/photogab/public_html/gabkits/includes/classes/db/mysql/query_factory.php on line 177
[19-Feb-2014 09:51:23 America/Denver] PHP Fatal error: Cannot redeclare date_diff() in /home2/photogab/public_html/gabkits/includes/functions/functions_general.php on line 1455
Also my server upgraded to php version 5.4 (from 5.2). But I asked them to downgrade so we can check if the site works but it didn't.

Can you please give me some clue on where to start poking?

thanks a lot!
