I'm using MobilePress and was adding to the UserAgent list and then this error showed up:
Warning: preg_match() [function.preg-match]: Unknown modifier '1' in /home/pattyspi/public_html/wp-content/plugins/mobilepress/system/classes/check.php on line 46
The page still loads and the theme does switch but it still doesn't make sense why it's happening. Clicking on the function.preg-match link removes it but it shouldn't be there in the first place. I reuploaded the original check.php file but the error is still there. How do I get rid of it? Some other file needs to be updated?
