@Matteo Beccati
Hello Matteo,
those are the definitions of the fields:
banners:
`append` varchar(255) DEFAULT NULL,
`prepend` varchar(0) DEFAULT NULL, (I've once set it to 0 to avoid some SQL injections we had in our installation and strangely doesn't fire any warnings)
zones:
`prepend` varchar(255) DEFAULT NULL,
`append` varchar(255) DEFAULT NULL,
Thanks and have a nice day
