I filled-up CDN settings with my Off-site URL and custom directories, but any images is served by CDN Url,instead if i click TEst Cache, cached version of my site has all images served by CND url.
see here http://bit.ly/fV7xek
I have already tried to delete browser cache and with another browser.
That's weird. I guess the best thing to do is use the debug system in the plugin. Also make sure that when a new page is cached, that the cached version is actually served. Maybe some other plugin is interfering somewhere.
Solved by remove gzip code from my theme
<?php if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start(); ?>
