Solved Help falling into the void

PLS help me!!
When a player of my server fall down into the void, a glass block is automaticly placed and the player is teleported to it, so the void under the spawn and the lobby is covered by glass.
I'm running CraftBukkit 1.8.8 and I have installed the following plugins:
Essentials, HideStream, LobbyCompass, MGOITC, MGSkyWars, MGSplegg, MiniGamesLib, Multiverse-core 2, UltimateSurvivalGames, Vault, WorlEdit & WorldGuard.

Any help is apreciated!!!

Thanks everybody

Sorry if I haven't post it in another category, this is my first post

 

Since you only have a few plugins on your server, follow these instructions:

Stop server
Rename one plugin from pluginname.jar to pluginname.jax.
Start server.
See if the problem is still occuring.

If it is, rename the plugin back to a .jar file and repeat the above steps.

Once you find the plugin causing it, either take the action you think is right, or reply back here and I'll try to help you decide what to do.

 

Thanks for reply me @oceantheskatr !!!
I will do it in my free time and I will tell you

@oceantheskatr I've done it and the problem is with WolrdGuard. I can`t uninstall it from mi server because it protects the spawn and the lobby from the others to destroy it, so I hope you can help me.
Here's my configuration file: http://pastebin.com/FAPvjxCJ

Antoher time; thanks for help me!!

 

I have solved it. The problem were in the world separated config file, in the "player-damage" section, option "teleport-on-void-falling".
Anyway, thanks for help me!!
