Help with Mediawiki article settings

Everything was working properly with my mediawiki website, and all of a sudden after editing the localsettings.php I am receiving an internal error page. I have since restored the original localsettings.php file, however, I am still receiving an error.

I receive the following error:
"Redirect loop detected!

This means the wiki got confused about what page was requested; this sometimes happens when moving a wiki to a new server or changing the server configuration.

Your web server was detected as possibly not supporting URL path components (PATH_INFO) correctly; check your LocalSettings.php for a customized $wgArticlePath setting and/or toggle $wgUsePathInfo to true."

I never changed these settings, but was wondering if anyone is familiar with what the settings should be. The current code reads:

$wgArticlePath      = "$wgScript/$1";
# $wgArticlePath      = "$wgScript?title=$1";

Code (markup):

Thanks in advance for your responses.

 

Still having this problem. Any solutions?
