Hello. I would like to insert a long descriptions. I saw that a description have 255 character (is a varchar). Can i change this for a TEXT or LONGTEXT? I change with phpmyadmin, but i think that i need to change the query.
You should only have to change it in phpMyAdmin. The queries do not specify what type of column it is except for install / upgrade (but it will not save over as it will recognize that column already exists).
