Version 1.4.4 NOT WORKING

I installed a fresh WP site (in a subdomain for testing), installed woocommerce, then installed Version WooCommerce Google Analytics Integration 1.4.4, after I added my property tracking code and enabled other settings, nothing is working, Tag assistant doesnt find any Tag , there is no analytic code in page source either!!
I successfully used this plugin in main domain a few days ago, but its not working now, whereas other WP google analytic plugin works well. Is it a bug ?
