When I try to join the server, I spawn at the hub, then transported to the main server. I fall for a second before being kicked for "Nope!".

I read some similar problems, one saying to delete a player file. By doing this I will lose my inventory, and I want to avoid that. If there is any solution to this without losing my inventory, I would like to know.

This is because you logged off sitting in a chair. Is there any chance you know where you logged out last? If we can find the chair you are sitting in, and break it, it will not kick you anymore, if we can't find it, we will have to delete your player profile

Is there a way to disable that?

No, we are looking into removing the plugin.

....ahem

chair:

enable: true <-- Change to false

require-sneak: true

regen-health: true

blocks:

Problem solved

Its located in config.yml

Uh, not sure if anyone (staff) knows about this but according to http://wiki.sk89q.com/wiki/CraftBook/Chairs

Under troubleshooting it says:

Did not realize we were using the chairs from craftbook...

I thought we were using the custom one we had made from firehead..

I was at a Blaze Spawner in /warp townfarm. I think I might have sat down in a chair inside the spawner.

the same thing happened to a friend he sat down at pig or cow sauna and is in the viod when he logs in and kicked for nope in less than a second

What would some side-effects of deleting my player profile? If loss of my inventory is the only side-effect I'm good, because I spawn in the void when I login now. So, I now have no inventory to lose.
