It is a code issue. I have no idea where but searches on that error, return half readable threads.

What I see though is this...

Код:

public OnPlayerTakeDamage(playerid, issuerid, Float:amount, weaponid, bodypart) 
{ 
    new Float:HP, holder[1000]; 
    GetPlayerHealth(playerid, HP); 
    if(weaponid == 4) SetPlayerHealth(playerid, HP-30); 
    if(weaponid == 22) SetPlayerHealth(playerid, HP-25); 
    if(weaponid == 32) SetPlayerHealth(playerid, HP-25); 
    if(weaponid == 28) SetPlayerHealth(playerid, HP-25); 
    if(weaponid == 30) SetPlayerHealth(playerid, HP-30); 
    if(weaponid == 31) SetPlayerHealth(playerid, HP-21); 
    if(weaponid == 34) SetPlayerHealth(playerid, HP-70); 
    if(weaponid == 29) SetPlayerHealth(playerid, HP-25); 

    if(weaponid == 25) SetPlayerHealth(playerid, HP-40); 

     if(!IsPlayerConnected(playerid)) return 0; 
      if(!IsPlayerConnected(issuerid)) return 0;

You set the players health, then check if they are connected.

You need to read your code a bit more. As was said above though, the full error, and highlighting of what line it occurs, is much appreciated.
