I need a plugin EssentialsX 1.11.2, because in base version it make a crash. Please help!

EssentialsX 2.15.0 is fully compatible with 1.9 to 1.12.2, as well as mostly compatible with 1.8 and unsupported but functional on 1.7.10.

If you're encountering a crash issue on 1.11.2, please report the actual issue in a new issue or on the Discord server.
