Hi
I have the same problem. My shop is installed in name_domain.com and the blog in the name_domini.com/blog and I work with a personalized theme in Prestashop, don’t with default theme.
When I configure the pluggin appears the next message:
The actual value “name_domain.com” does not refer to a PrestaShop installation !
Please check your installation or this plugin will not work !
Regards
