Solved Error when <player> receives damage

Error when <player> receives damage and tries to pass to Essentials Protect.
Recently I installed Essentials Protect to block lava flow. But after fooling around with the settings of it and configuring it I checked the logs to make sure nothing was going wrong. To my suprise I noticed an error. I examined it, and figured out that it was cause by any <player> receiving damage from another player.

Code:java

[14:09:10] [Server thread/ERROR]: Could not pass event EntityTargetEvent to EssentialsProtect v2.12.2

Please tell me how I can fix this problem and notify me if I posted this wrongly, or you have a quick fix.

 

It appears to be an error with essentials, make sure it's updated to whatever version of bukkit you have installed.

 

Well you see, I realize it was essentials. I actually know it was EssentialsProtect to be precise. I am supposed to be using non-dev build for a dev build of essentials?

 

I hate Essentials Protect...

You said you were using it to stop Lava Flow.

I suggest you get rid of Essentials Protect and get WorldGuard. It can do all that and a LOT more, but I've never had issues with it.

If that seems unhelpful tell me xD I will try and solve it, but I've never used Essentials Protect because it causes nothing but issues for me.

If you're willing to switch. I would do it...

 

Update all essentials jars to the same version. The error here means it cant access essentials.jar API.

lecraeman If he is only blocking lava flow, then that would be a big overhead added for just that.

 

WorldGaurd didn't seem to work before, If I remember correctly. I will give it a try right now.

Edit: Disabled EssentialsProtect and created a region in worldgaurd. Then created a flag for the region to disabled lavaflow. Word perfectly. Thanks

(Marked as Solved)

 

You already had world guard? There's an option in the config to COMPLETELY block it everywhere, but whatever works for you

 

Is there really... OMFG what ever, I got it work. With it now working I am one step closer to opening my server to public. Thanks for your help

 

No Problem

If you need any more help tag me in a thread!

 

of course bro,
thanks again!
