Force SSL checked, but doesn’t work

First, this is a WooCommerce setting, not related to this plugin, so post it in the correct forum.

Second, you may be having a conflict with a security plugin, so check this.

Third, is you site capable of using SSL?

I wrote “WooCommerce”, not “WordPress”. The Force SSL is a checkout setting in the shopping cart plugin, not the payment gateway itself.

Any security plugin installed on the site?
