Thread:Project:Forum/Infobox not working/reply (14)

Unfortunately, importing that template and making it work isn't an easy thing for me to explain. :/ I'm going to look at the rest of what you've got here.

Remove the four lines after the $wgPFEnableStringFunctions line. You shouldn't be including those directly; ParserFunctions.php will take care care of that. The rest of this looks a bit odd. You have at least four extensions installed according to this, but none of them are showing on Special:Version. There should also be a Special:CategoryTree page, but there isn't.

So these extensions aren't installed. Since you're using require_once statements, a missing file would result in your wiki not loading at all. So it seems that those statements aren't even being read in the first place. You're doing this in LocalSettings.php, right?
