Thread:Project:Current issues/MobileFrontend and Mantle problem

I cannot update my wiki with Mobilefrontend. I added the appropriate code in my Localsettings.php. I downloaded the latest version of Mobilefrontend. I then downloaded Mantle 1.25 and put it in my extensions. When I go to my wiki it says please install Mantel. Does anybody know whats wrong. I am using Mediawiki 1.24.2
