Reasons experienced by me that cause pawno to crash:
1: An un-terminated strin, EX:

PHP код:

SendClientMessageToAll(-1,"Hi); 


See after "Hi << there isn't another " to terminate the string.
and it should look like this :

PHP код:

 SendClientMessageToAll(-1,"Hi"); 


2: An unmatching closing brace, for EX:

PHP код:

public OnPlayerConnect(playerid)
{
    SendClientMessageToAll(-1,"Someone connected");
    }
    return 1;
} 


see on the code above we have one { and two } so remove one the code should've looked like

PHP код:

public OnPlayerConnect(playerid)
{
    SendClientMessageToAll(-1,"Someone connected");
    return 1;
} 


And the vise versa you might have two {{ and only one } so review your code and see where you fucked up.

these were the reasons that I KNOW OF idk if there's more or not.
