Thread:Project:Support desk/MediaWiki hosted on MAMP upgrade

Hello, I'm wondering if anyone would be able to help with a problem that's been occurring after installing a Mediawiki update for a private wiki that is hosted locally using MAMP. Following instructions on the Mediawiki site and other user advice, I replaced the the older version of MW (18.1.2) with MW (18.1.3) in the MAMP/htdocs directory while preserving the old localsettings.php file. After following instructions within the wiki program, the upgrade to MW 18.1.3 was complete and it provided a link to follow to use the wiki, just as it did when I first installed MW (18.1.2). However, this time it comes up with following error message: "The requested URL /mediawiki-1.18.2/index.php/Main_Page was not found on this server." It's clear that I missed a step when upgrading the wiki to make it available on MAMP in its new form. If I type in the usual "localhost8888" it shows an available link to Mediawiki 18.1.3, but once I've followed the link, the error message comes up. I've tried typing in localhost8888: mediawiki-1.18.3/index.php/Main_Page, but that doesn't work either. The PHP version is 5.3.6 and the Database is MySQL 5.5.9. I'm a newbie (probably obvious by the mistake) and it would very helpful to receive guidance. Thanks!
