Don't buy if you value keeping your plugins updated. They will not supply you with updates for Revslider and Visual Composer. Every other theme I've ever purchased does this but they won't. Terrible customer service.

Hi, There is misunderstanding here,
To update our plugin include on our theme. Please delete current version then click re-install on top message about plugin requires,
We bought an extended license to be able include it in our theme, and we own only one license key (as well as in case with single license), theme buyers are not allowed to use that key.
Please contact us via ticket system, https://wpopal.ticksy.com/ we will support for you. Thanks
