I have my wp installed. I have themeforest installed, but I have never upgraded it. That is my problem.
Tell me what you will charge me to update this theme. What I never liked from this theme is, that we never could share to twitter, facebook, etc. When we tried to do so, the site goes off. It happened several times. Gracias.
