Aha okay. The "takePlayerMoney" is in client and "giveWeapon" is in server. Sooo I must switch these so Money is set as server and weapon in client?

Hello I have a big problem... On my zombie server players can buy weapons for etc 12000$ and reconnect or kill a zombie then they get their money back. It happends every time. I looked through "weaponshop" and script for problems but I couldn´t find anything and I tried to find out in wich script the bug was, but i didn´t find it. Some suggestions?

It have happened to me. It was when I had moved the server folder to somewhere else on the pc that was stupid of me. And also it must be the 3 right ports. One you don´t have to change, 22003 and 22005, but probably you allready changed that in the mta config. You don´t have another server that´s use those ports?
