I've just installed this plugin, with the most recent of updates and I can plant everything everywhere. All settings are set to "true". Is it possible that with me being the server owner, I overrule this plugin?

Bit of an oversight in the code when you only plant one seed. Working on a solution now.

Thank you for getting back to me with an answer so fast. I'm pretty excited to gettting this set up on the server not only to keep the entity count down, but moreso to make planter boxes more useful than they currently are. Thanks for your work on this plugin.

@CSwords Please try the latest version!

The latest version works like a charm for me. Thanks for such fast work!
