nicholas_io on "[Plugin: Visual Form Builder] VFB does not delete database tables when delete a site in a Network"

Hi, I'm using WordPress 4.0 Multisite instalation, and I realize that when I create a new site It works fine, but when a delete a site inside my network, the tables of visual form builder related to that site still on the database. I think this need to be fix'it to avoid keeping trash on the database.

Thank You!
