not quite enough detail to offer any help. Server version 1.12.2 is nice, but what type of server (Spigot, Bukkit, Forge, Paper, etc.) What other plugins do you have installed? Can you provide a link to the full startup log? That will uncover where the problem may lie. FWIW, I have the same version 2.13.6 (shown in your screenshot) on Spigot 1.12.2 (4 builds behind current) and don't have any issues with the 50 other plugins with it.

Thanks - just the startup alone as I thought uncovers many issues that can contribute to one or more other plugin failures.

1. DiscordSRV-Build-16.0.jar, FastAsyncWorldEdit.jar fail before this plugin did and could be contributing to it.
2. Essentials Plugins - they all MUST be the same version and you are not on the latest for any of them. You'll see Version mismatch! errors for all 6 plugins - that's telling you they are not compatible with one another.
3. Slimefun has registration warnings and CMI plugin fails along with Factions.
   What you want to to is get all your plugins to not have failures during a startup first and foremost. Then figure out what's going on afterwards. Make sure you are running the latest versions of "ALL" plugins matching the release of Craftbukkit.
   Hope this helps. :-)

The main issue with this is going to be with Essentials: I'm using EssentialsX on all of these Essentials plugins, and there are no other updates for EssentialsX, I've downloaded the recent build and it's still giving me the errors (saying that it's outdated). I'll have to run the server without those plugins and them run with them to try and see what can work and what can't.

Make sure you are getting them from here, the official page: https://ci.ender.zone/job/EssentialsX/ - the latest for each is build 595. Each one would be downloaded directly and then remove the old ones (dup jar's will cause problems also).
You'll know you have the right versions for each of them when the versions are part of the file name shown at startup. If it still say b2.0.1-SNAPSHOT (it's very old) and not the recent one. That's a bug they fixed in the high 400's.
