Hey, i have downloaded a Forms plugin to my Invision Forum from here, getting this error, i know its built for an older version but i have no idea how i can downgrade my forum version.. also i red about an option to use old plugin / plugin that built for another version by changing something in the DB.. is that possible? any other idea on how i can use this App? or maybe there is another App for forms that i can get for free? Thanks.
