HI just bought and downloaded Avada theme and I keep getting this error. I deactivated all my plugins too. I know some people say do it through FTP but I have no clue what that actually means. <strong.Please help!!!
You are right that FTP is the way to resolve this.
All you need to do is to download something like FileZilla then get the ftp details from your hosting admin account and install the theme manually
This is a common error but has an easy fix, see this post: http://theme-fusion.com/knowledgebase/are-you-sure-you-want-to-do-this/
