What is this Error?

[karazu 33]

can anyone tell me how to locate or give me idea why did error came out?

Your NPC called 'Versus' is trying to delete some items an user doesn't have, then making that error appear.

 

I'd suggest changing the

delitem 7420,10;

On the source of that NPC for something like this:

// Rest of NPC hereif ( countitem(7420) > 10 ) {	delitem 7420,10;	}else if ( countitem(7420) > 0 ) {	delitem 7420, countitem(7420);	}// Rest of NPC here

 

This way, the error should be gone.

check your script maybe you can see where is the problem. if you check the error console, its showing the your script have an npc name Versus which is invisible or not on a map

Maybe that Versus script is in your custom folder and added by you, but it's just in the same file as another NPC.
