My client switched hosts, and now Silverstripe is throwing an error on every page:
mb_ereg_replace() [function.mb-ereg-replace]: mbregex compile err: unmatched close parenthesis
Line 494 in sapphire/core/SSViewer.php
Surely this has something to do with the mbregex module configuration? I've seen very little written about this. I've tried changing the mbstring.func_overload to a number of different values. Nothing seems to work. Very frustrating!
