Thread:Project:Support desk/Unable to implement any extensions

http://www.edgeofforever.dreamhosters.com/wiki/index.php?title=Main_Page

Product	Version MediaWiki	1.19.2 PHP	5.4.11 (cgi-fcgi) MySQL	5.1.53-log

I have tried to install and use a dozen or so different extensions on my wiki without success. As almost all of the instructions say, I have FTPed the extensions to wiki/extensions (sometimes in folders sometimes directly into the directory). I have also added the line to my LocalSettings.php file at the very end of the file like this: require_once("$IP/extensions/extensionname.php"); or require_once("$IP/extensions/directoryname/extensionname.php"); None of the extensions I tried ever showed up on my Special:Version page nor did they ever seem to be installed on the wiki.

I've done some pretty extensive searching trying to solve this issue, but I never found a thread where someone had the same issue, which is what brings me here. I'd appreciate any help you can give me!
