Footprints on the Moon

Well, I came over here with the intention of writing about discount home theater seating, only to discover my blog developed a string of errors overnight. I’ve spent some time looking and trying to find the cause of the error, but I’m not having much luck. Anything I’ve found out there doesn’t make sense to me. I didn’t change anything before the errors cropped up, so I don’t even know where to start!
The error looks like this:
Warning: preg_match() [function.preg-match]: No ending delimiter ‘!’ found in /home/footpri1/public_html/wp-includes/classes.php on line 95

If you’ve got an idea of how to help me fix the problem, I just might love you forever! It also appears to be only on some pages– it’s on the main page, but not the individual page for this post. It’s also in the manage tab on the admin side.
