Support

Three things make a first reply useful instead of a request for more detail: which plugin, which version of it (the Plugins screen in WP Admin shows it), and what you saw — the screen, the message, what you expected instead. A screenshot says most of that in one go.

Licence questions are support too, and they are welcome: a key that will not activate, a key you have lost, a renewal, a refund inside the fourteen days. Those go quicker if you write from the address you paid with.

Docs cover each plugin page by page, and FAQ has the short answers to what gets asked most.
