That gamemode is probably outdated. Sscanf has been updated and you need to include the latest version, plus update the mode. The function you mentioned before was removed "AllowAdminTeleport" and you can use the callback a user posted above. It does the same thing.

From what I see from the errors, you have removed the first lines with the includes/defines. And in line 1 is the OnGameModeInit callback. Include a_samp.inc, Dini.inc and a_mysql.inc
