I have subscription for Gavick but I can't see the forum for Gavick Joomla Templates. I am using GK Appetite and the answer of my question is actually here https://www.joomlart.com/forums/d/45502-how-to-edit-social-share-block-gk-appetit but I don't have access. I get "You need a valid subscription to view replies."
