Hello.  My gallery works perfectly on desktop computer but doesn't seem to be working on mobile devices.  I have multiple galleries using different Flickr sets and when I try to view on mobile, it reads "Cannot load from Flickr." Here is my .xml file:

<?xml version="1.0" encoding="UTF-8"?>

<simpleviewergallery

    useFlickr="true"
    flickrUserName="sugarcoatedinc"
    flickrGroupId=""
    flickrSetId="72157627396246892"
    thumbPosition="BOTTOM"
    thumbRows="2"
    thumbColumns="9"
    thumbWidth="50"
    thumbHeight="50"
    showOpenButton="false"
    imageFrameStyle="ROUNDED"
    imageNavStyle="cursor"
    imageNavBackColor="FFFFFF"
    thumbFrameStyle="ROUNDED"
    thumbNavStyle="NUMERIC"
    thumbnavposition="BOTTOM"
    thumbNavColor="FFFFFF"
    thumbNavHoverColor="FFFFFF"
    thumbNavBackColor="FF0066"
    showNavButtons="true"
    buttonBarPosition="BOTTOM"
    buttonBarVAlign="CENTER"
    buttonBarHAlign="CENTER"
    buttonBarBackColor="FF0066"
    enableCaptionLinks="false"
    showImageNumber="false"
    floatCaption="false"
    captionPosition="NONE"
    backgroundURL=""
    galleryWidth="100%"
    galleryStyle="CLASSIC"
    frameWidth="0"
    imageScaleMode="SCALE"
    imageClickMode="NAVIGATE"
    imageHAlign="CENTER"
    imageVAlign="CENTER"
    imageAreaX="280"
    useFixedLayout="false"
    indexPageName="celebrationcakes.html"
    backgroundTransparent="true"
    thumbPadding="2"
    thumbPreloading="PAGE"
    thumbFrameWidth="2"
    thumbLoadBarHeight="10"
    backgroundColor="FFFFFF"
    imageBackColor="FFFFFF"
    showDownloadButton="true"
    flickrImageCount="500"/>

I'd appreciate any help! Thanks!
