Admin login page shows php error messages

Wanting to know if anyone knows what could possibly be the issue here when we go to our admin page before even logging in… this message appears in the upper left corner…



Warning: preg_match_all() [function.preg-match-all]: Compilation failed: unknown option bit(s) set at offset -1 in /home/lotusm/public_html/core/fn.common.php on line 1459



Warning: array_reverse() expects parameter 1 to be array, null given in /home/lotusm/public_html/core/fn.common.php on line 1460



Warning: join() [function.join]: Invalid arguments passed in /home/lotusm/public_html/core/fn.common.php on line 1460



We have submitted a ticket to supoort but they are back logged and won't be able to take a look until next week…



We are using php 5.3 because it seemed like php 5.4 was causing major problems.

We are running CS Cart 3.04…



Thanks!!
