Before updating, save the dump of the "ms_settings" table via the "shop/admin/?page=db"admin panel. Go to "shop/admin/?page=settings". Run a MySQL query via phpMyAdmin to clear the table with the settings:
TRUNCATE TABLE `ms_settings`; ALTER TABLE `ms_settings` CHANGE `name` `name` VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;
Replace the files with new ones and refresh the page with the settings "shop/admin/?page=settings" F5 and click "Save" at the bottom of the form. Also save your settings: "shop/admin/?page=smtp", "shop/admin/?page=bans", "shop/admin/?page=lisf-geo", "shop/admin/?page=lottery", "shop/admin/?page=steam", "shop/admin/?page=telegram", "shop/admin/?page=viber", "shop/admin/?page=referal", "shop/admin/?page=upload", "shop/admin/?page=adm-mctop", "shop/admin/?page=adm-topcraft", "shop/admin/?page=adm-mcrate", "shop/admin/?page=adm-fairtop", "shop/admin/?page=adm-minecraftrating".
