Thread:Extension talk:MobileFrontend/Mobile Search Broken

Search on the mobile side of the extension is broken for me, but there appears to be a problem with MediaWiki's API. Below is an example that compares my API with the API on Wikipedia. Both API params are exactly the same.

http://wiki.kappakappagamma.org/api.php?action=opensearch&format=xml&search=kappa http://en.m.wikipedia.org/w/api.php?action=opensearch&format=xml&search=kappa

As you can see the first URL returns back a JSON result rather than a xml result. Wikipedia has the correct result. I did not make any edits to the API of my installation so I am curious on why this is occuring. Does anyone else experience this?
