Sziasztok, az lenne a problémám, hogy van egy mysql összekötető scriptem, jók az adatok, minden ki van töltve de ezt irja folyton a console-ba: [2016-10-24 20:53:13] ERROR: sql/connection.lua:17: attempt to call global \'mysql_connect\' (a nil value)
több scriptel is próbáltam de akkor is ez a helyzet. Házi szerón, és
hostolt szerón is ez van. Mi lehet a gond?
