When calling the "page info" item, it just shows a small red-bordered rectangle telling "Info failed".

The error "Info failed" obviously results from the following code in ext.info.js:

                var postArgs = { action: 'info', titles: mw.config.get( 'wgPageName' ) };
                 new mw.Api().post( postArgs ).then( function () {
                        location.reload();
                }, function () {
                        mw.notify( mw.msg( 'info-failed' ), { type: 'error' } );
                } );
