The issue was http vs https in the ftbguides code as the website changed.  It was fixed in github 2 days ago and a new version pushed 1 day ago of ftbguides however just updating to the new version of ftbguides doesn't fix the issue.  We'll probably have to wait for a pack version to update.  I am sure 
@slowpoke is all over this and we can expect a working version shortly...
