I don't know what shop.lua you got but heres mine and it works perfect

-- ### CONFIG ###
-- message send to player by script "type" (types you can check in "global.lua")
SHOP_MSG_TYPE = 19
-- time (in seconds) between connections to SQL database by shop script
SQL_interval = 30
-- ### END OF CONFIG ###
