In functions_newpost.php FIND
PHP Code:
function convert_url_to_bbcode($messagetext)
{ // the auto parser - adds [url] tags around neccessary things
BELOW that ADD
PHP Code:
return $messagetext;
This will disable autoparsing of URLs everywhere.
@NTLDR
This would not stop ppl from using autoparsing, if would just hide the controls (or uncheck it).
And what about private messages? Editing posts?
