There is an error in TAG system.When I enter game it didnt give any error .But TAG system dont work.I found an error in Client log:

0519 18:38:13269 ::  !! PARSING ERROR - Strange Command : DEV

This is the part of the code gave this error:

if gamemasta2.find("[DEV]")!=-1 and constInfo.GM_MARK == 0:

            constInfo.GM_MARK = 1

 

I opened a char. named [DEV]Night It shows no tag sign on him.

what can be the problem ?
