Editing messages with embedded image(s)

For some reason, all of a sudden embedded images



are resulting in not only the image showing inline in the message, but also full size int he attachments area. Weird. Now if you edit a message like this, and Go Advanced, you will see Javascript errors and mangled layout. A close look reveals

Warning: preg_match() [function.preg-match]:
Compilation failed: invalid range in character class at offset 23 in [path]/includes/class_wysiwygparser.php on line 458

This is happening within the forum scripts on the server end (PHP). I'm not sure why this "just started happening". It is not a browser issue, it's happening in Chrome and Firefox. I'll try to zero in on this when I can.

I have determined that this was caused by an upgrade of the MySQL database on the Linux server that hosts the Comm Center. That's a relief, at least it wasn't like the Syrian Electronic Army hack we had a while ago!!

OK, it looks like I have stamped this one out, thanks to a simple fix in the vBulletin Forums. The interesting thing is that the regular expression was indeed illegal, but it was accepted by the old PHP/MySQL. When they upgraded, the new stuff checks better and flagged it.
