This message is on my site above the header:
Warning: preg_match() [function.preg-match]: Compilation failed: unrecognized character after (? or (?- at offset 3 in /home3/healtio8/public_html/wp-includes/classes.php on line 210
I also appears at the top of dashboard at times. I've deactivated all of my plugins with no change. I've also upgraded everything.
Anyone know what to do???
