This is likely the simplest issue ever. But I did not write the code and its not commented. I am just trying to fix it because its causing a lot of issues on my site. Its in the main text parser code.
Error: preg_replace(): Unknown modifier '\'

There is a lot of it so this is the simplest way to do it. $text is the parameter. Looks like its a bad word filter but seems to be missing with lots of things. I can't find out what is being passed sorry. Unless you know of a why that I could.
$text = preg_replace( '/(^|\W)' . preg_quote( $test ) . '(\W|$)/i', "\\1" . $replace . "\\2", $text );
