On the 1st October Facebook have mandated that all external content hosted on fanpages or in applications must be secured over an SSL. If your fanpage or app uses externally hosted content it but be referred to using https rather than http from this date.

If you use your catalyst2 account to host content for your facebook app we can supply and install a recognised SSL certificate for £99/yr that will allow your content to keep working seamlessly with your Facebook page/app.
