Getting Error

[oshrizak]

Ok dont know what caused this but I am getting this error when trying to post a thread and I can not edit a thread.

Error:
Warning: preg_replace() [function.preg-replace]: Compilation failed: lookbehind assertion is not fixed length at offset 176 in [path]/includes/functions_newpost.php on line 247
{"ajax":"save","error":"Invalid Message Specified"}

This has just showed up and the Forum was working fine yesterday. If I disable the plugin/hook system the error goes away??? any advice?

:confused:

Did you just have your server software upgraded to PCRE 8.21? If so, you need to downgrade it to PCRE 8.20 as there is a bug in it that causes issues with the vB software.

Ok will contact server Admin to sef it has been upgraded because this just started happening
