Thread:Project:Support desk/Skin.php suddenly failing to open correctly

I run MediaWiki 1.2.0. This problem may be somewhat related to Scribunto, which was also the v1.2.0 version, though I disabled the extension.

This all began with a seemingly simplistic install of Scribunto in order to support a plethora of Wikipedia infoboxes and various other templates. Somewhere along the way of troubleshooting why the standalone Lua engine wasn't working I ran in to an error which seemed to quickly deteriorate. At first, it appeared that my wiki had lost its Vector skin, being reduced to the basic skinless format. Shortly after, without editing any files, I became unable to access the wiki altogether with the below error.

Warning: dir(/home/content/54/10246254/html/wiki/skins) [function.dir]: failed to open dir: No such file or directory in /home/content/54/10246254/html/wiki/includes/Skin.php on line 57

Fatal error: Call to a member function read on a non-object in /home/content/54/10246254/html/wiki/includes/Skin.php on line 60

I have the default Skin.php - I have even matched it against raw versions online. It has never been edited, but the line reading the following is marked as an error: $skinDir = dir( $wgStyleDirectory );

Does anybody have an idea what is happening or how I can fix this? I enabled $wgDebugLogFile and set it to the appropriate directory in my LocalSettings, but no error log is being produced. I am very new to this and fear losing my progress on my wiki thus far for I have no backups. Sorry if I have failed to provide enough information, I run this wiki off of a GoDaddy server running off of a Linux dist.

Thanks.
