Any help would be appreciative...

Interesting that the error is about "mb_ereg_replace", even though that line the error occurred on has "ereg_replace".

Is there anything special about php on your host? I've never seen this error before.

You could try supressing warnings and see if your site still functions. Generally its a good idea when running in live mode (production) anyway.
