With a little more Digging (and a bit of Learning on the Regular Expresions). I have tracked this problem to the First preg_match search string. Why the Error?
I'm not sure. Though the repetative nature of the string could be the main problem.
I have modified the Realmstatus.php on my site with a little of the old and new mixed together.
By using substr and strpos to strip out 800 characters out of $html and using the preg_match_all statement. I have, at this moment a working European Realmststus. Will need to wait for Wednesday to see if it will show up with an Offline Image though.
I have attached the File (Use at your own risk). I would suggest you back up the old realmstatus.php first.
By the way. for those interested. I'm running a Win2003 Server.
