I have submitted a report 1 month ago and still did not get any response.
1. I have problem with Configure your shop to be fully HTTPS. When I follow your instructions to enable HTTPS, my order view got error popup and some become blank.
2. for the Optimize images cache, my hoster told me that they already enable php exec() but when I check, I still got PHP exec() function is not allowed at your server.
By the way, I bought the lightning license.
