First open <b>/sources/lib/post_parser.php</b> and find <b>if ( $in['CODE'] == 1 ) {</b> in the file. Below that add <b>$txt = preg_replace( "#\[spoiler\](.+?)\[/spoiler\]#ies", "\$this->regex_spoiler_tag('\\1')", $txt );</b>
Etc... Just do what it says. Add after, add before, replace. Those are the basic procedures. Can't get much simpler.
I'm editing the php just like it's telling me and it's still not working, I'm even copying and pasting to see if I can get it right. Can somebody edit this for me? It's not going well for me.
