I’ve been using S2 Pro for a couple of years, but suddenly, the Pro version isn’t being detected. Within WordPress, I can only see the free version activated, even though the Pro version is on the server like it’s always been. How can I fix this?
S2 Framework no longer detecting Pro version on server
It sounds like the two versions are out of sync in terms of version number. I would suggest logging into your WebSharks account to download the latest version of Pro, and then uploading it via FTP (the way you did when you first installed it).
