TNT doesn't blow up

If I light TNT it just fizzes and then disappears. Any players next to it are killed.
My Plugins:
Multiverse-Portals
CommandBook
WorldEdit
NoLagg
Multiverse-Core
Essentials
WorldGuard
InfiniteClaims
TimeLock
MultiInv
Modifyworld
ChatManager
PermissionsEx
ChestShop
iConomy
SimpleChestLock
InfinitePlots
PluginMetrics
craftscripts
Is this fixable?

 

Try removing nolagg as it may be removing the explosion animation.

 

It could be WorldGuard, Essentials or NoLagg causing this issue. Check all those configs and see what you find.

 

Hm, I got NoLagg and might see if it IS causing the prob now.

 

Uninstalled NoLagg, now i'm going to try the others because that didn't work but thanks for the help.

it was disabled in essentials, thanks very much. Nether Portals didn't work so I installed the nether plugin for multiverse but now it says "This Portal Goes Nowhere"
