I purged the cache, and then deleted the plugin, and cache folder as well. The applications which loaded the images, and not updating. If I clear the cache on the phone for the Application, it is working fine. I have also cleared the .htaccess.
I cannot ask each user to clear their cache! ?? Very strange! I was not expecting this from w3Total Plugin! Which has more than 1 million installations. Please share if you have any solution. Thanks
