Plugin Help Essentials stopped players taking damage from mobs

I run a FTB Departed server for a few of my friends and today I installed Cauldron on the server so I could run essentials. I got it all working properly, tp home warp etc works fine, but not of the mobs do damage to players. As departed is based around the Advent of Ascension mod, a RPG style mob battling mod, this is a problem. I have checked and I can still take fall damage and when the hunger bar is 0 I take damage to half health as per usual. Both vanilla mobs and AoA mobs do no damage to players and in fact, in the case that you do manage to take damage from falling or something, they heal you up to full on hit. Does anyone know what the problem is, is there a config I can change to rectify this or do I have to get rid of essentials (worst case scenario).

 

So it happend asoon as u installed essentials? cause i never seen essentials do this for any of my servers if so try removing it and see what happens

 

Yes I took cauldron off so essentials wouldn't run and the damage from mobs returned

 

Check config file if there's something you can configure, I think you have accidentally triggered NoDamageFromMobs
