Recently we got upgraded to php5.4 and have had some problems with accessing anything on the server. Found out that removing the php.ini file from the server fixed the issue but this one is not wanting to comply.

This mod is for vendors to access the backend of the store to input their product information and images and when going to the link you should get a login box:
http://fantasiesrealm.com/market/privatearea/login.php

instead we get this error message on the page I also have gone to the cache folder both in main store folder and the private area folder but there is nothing in there.

I have gone to creator and left a work ticket about it in case he has a clue too.

Fatal error: Cannot redeclare date_diff() in market/privatearea/includes/functions/general.php on line 3058
