It's actually a loop that goes over the regexes that I'm not exactly sure why it's there.
Editing ubbthreads.inc.php seems to fix this. Around line 988 of that file there is a block of code that looks like this:
while( $x && ( $loop < 10 ) ) {
$loop++;
foreach( $regexes as $z ) {
if( preg_match( $z[0], $body ) ) {
$x++;
$body = preg_replace( $z[0], $z[1], $body );
}
}
} // end while
We need to comment out the loop, like this:
//while( $x && ( $loop < 10 ) ) {
// $loop++;
foreach( $regexes as $z ) {
if( preg_match( $z[0], $body ) ) {
$x++;
$body = preg_replace( $z[0], $z[1], $body );
}
}
//} // end while
