'return 1' belongs inside the function block of OnPlayerDisconnect; between the curly brackets.

This is what you had in your original post:

PHP код:

;
public OnPlayerDisconnect(playerid, reason)
{ 


I don't think that semicolon (';') should be there. But I can't tell, if you're not willing to show me the code right above it.
