I purchased Revolution Slider on 10th April 2018 and managed to activate the plugin and use it for several months. I could use all the “direct buyers” benefits. In the meantime the support time from the developer passed. Just recently I’ve discovered that the premium access is locked as if I didn’t activate it, as if I didn’t buy it. The only thing that changed is that I changed my domain from http to https, but I’m not sure if it is the reason it stoped recognizing my purchase code.
So I tried to deregister the domain and register it again. I did all that was required (made api etc.)
When I click the “Register Slider Revolution” button
a transparent window appears and in the top right corner It says: “purchased code succesfully activated” but the plugin stays INACTIVATED. I tried it few times.
I’m writing that here because there’s no way to contact the developer unless I pay for additional support service period. I feel that would be unfair, because the only thing I want from them is to activate this Revolution Slider and get it to work as it used to work.
