Hey Amin, I'm trying to get this functionality working too. I have a customer who is using all of the above and when I click on a button using the new estore code, the page generates this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/cooking/public_html/wp-content/themes/OptimizePress/members-style1-contentUS.php:3) in /home/cooking/public_html/wp-content/plugins/eStore-extra-shortcodes/shortcode_include.php on line 909
Any ideas?
