       I tried to install GeoData  many times , there is on time install success , after i edit a wiki page and click save , i got a Database Error. then i open database  and found what i edited in page was correct saved in tables,i don't know why i got  Database Error.  I can sure it is the problem with GeoData because after i remove GeoData ,everything working well.

       then i try to install Nearby follow this https://www.mediawiki.org/wiki/Extension:MobileFrontend#Install_Nearby and set $wgMFNearbyEndpoint = 'http://en.m.wikipedia.org/w/api.php';$wgMFNearby = true;in my LocalSettings.php ,but when i click "Nearby" in app , it show " there are no nearby list" ,is that something wrong 
    with $wgMFNearbyEndpoint= 'http://en.m.wikipedia.org/w/api.php' or i missed something ?
