Please make sure you write your game mode name to server.cfg same as it's in your game modes folder. This happened to me when I Didn't write game mode name correctly, or I Din't put my game mode .AMX file to game modes folder. SA-MP loads .AMX file, not the .PWN file. PWN file is for scripting/editing.

If this doesn't help you, then please use server native checker plugin. Link can be found from Avi57's reply in up and make sure you are using newest plugins and includes, etc.

Thank you.
