Hi All,

From this morning the mobile api returns a 500 status code error

here is the error

If you report this error to the Wikimedia System Administrators, please include the details below.
PHP fatal error in /usr/local/apache/common-local/php-1.20wmf2/extensions/MobileFrontend/WmlContext.php line 12: 
Argument 1 passed to WmlContext::__construct() must be an instance of ExtMobileFrontend, none given, called in /usr/local/apache/common-local/php-1.20wmf2/extensions/MobileFrontend/api/ApiParseExtender.php on line 72 and defined

here is the url

I got this error for all the pages I tried.
Yesterday I was getting the data, was there a change in the API? When I remove the mobileformat parameter I get the data.
Thanks
