Can't break items on my server

This is my vanilla server, I am using spigot and bukkit and I recently configured essentials on my server, I've been having a lot of problems with breaking blocks (the newer players) even though all of the groups have block breaking enabled, I've deleted all of my plugins (except essentials) and the same result happened. Here is the plugin list, and the message, "You are not permitted to interact with SMOOTH_BRICK".
-AutoRestart-Reloaded
-Clearlag
-Essentials
-EssentialsAntiBuild
-EssentialsChat
-EssentialsGroupManager
-EssentialsProtect
-EssentialsSpawn
-Factions
-MassiveCore
-Vault-1.4.1
-worldedit-bukkit-6.1.5
worldguard-6.1

What happens if you remove essentials? If the problem persists without essentials, then there is an issue with one of the server properties. If removing essentials fixes your problem, you have not given the build permission to those players.

 

That's EssentialsAntiBuild. I believe the correct node to add is "essentials.build.interact.*" (Without Quotation Marks) will fix that. You can also remove EssentialsProtect and EssentialsAntiBuild to fix this. (I don't use them, because WorldGuard is a better solution).

 

Ah, you're correct. Forgot that was part of Pex. I will edit my earlier post.
