I am using the Facebook JavaScript SDK for a project I’m currently working on. It’s been working fine before, but when I opened it today, the URL http://connect.facebook.net/en_US/all.js is not accessible. When I inspected the network using Firebug, I noticed that the server was returning 403 Access Denied.
Is there something I am getting wrong or is it Facebook server problem?
Finally figured out that Facebook’s new HTTPS feature is interfering. Using https://connect.facebook.net/en_US/all.js solves the problem. Seems someone misconfigured their servers.
