Unable to turn off god mode

I have had myself i want to say "glitched" into god mode somehow, and its the same for all OPs. If you have OP rights on my server, lava, fire, tnt, creatures, etc cant hurt you. Players can, and creatures can if i attack them first. I want to take part in dueling arenas with lava pits and such, and as of now i cant because i have an unfair advantage over normal members, and we all want a fair match ya know? A list of all of my plugins as follows, but its alot -_-

adminchat, bigbrother, civilizedspawn, dropbonus, easytp, essentials, flyridgefly, groupmanager, iconomy, izone, kitplugin, levelcraft, localshops, lockette, magiccarpet, mcstats2, monstertamer, nodrop, war, worldedit, worldguard, worldwarp, wormholextreme

So many i dont know where to start....

 

its probably WorldGuard and Essentials conflicting in some way, try using a list to show plugins
like this:

• adminchat
• bigbrother

etc.
