Thread:Project:Support desk/Inherited an old wiki. Unable to change LocalSettings.php and have it register modifications.

I inherited an old wiki. I was told to clean it up (spam, etc). right away I wanted to stop all new user accounts and edits until it's cleaned up. I modified the LocalSettings.php and re-committed the file to the server. Wiki does not change. I modified the LocalSettings.php file to something simple, like a skin modification, but ultimately, the wiki does not change. It acts as if the LocalSettings.php file does nothing, or it's being referenced by a different LocalSettings.php file.

I downloaded the whole wiki and searched for other LocalSettings.php files. I found only the one I was working on.

Any ideas? I have no background on how this wiki was created and how it might have been customized. I have my own MediaWiki site that I've managed and it works fine. I even copy and Pasted the contents of my functioning LocalSettings.php file into the new dysfunctional php file (minus the credential stuff), and it still didn't work.
