you did not enable it in the configuration file
open the configuration file, find the group you want among: Default, vip1, vip2, vip3
and you need to set these fields
"Enable Customization. Default false": true,
"Limit of planters box that can be automated. (-1 no limit) (0 disable entity). Default 0": 0,
instead of 0, you can put the limit you want, or -1, without limits
save the file, and restart the plugin.
then based on the group you choose you have to assign yourself the permission, if you have configured the vip1 group, you have to give yourself the permission: ultimateindustrialfarm.vip1
