Certificate extension is invalid "blob" when adding social key and secret

When I try to add a key or secret to the app social setting, I am getting error message "Certificate extension is invalid “blob”, then the saving message spins and nothing gets saved. This is happening on existing accounts and a new account i jsut created.

I the problem has gone away. i had configured the app to use a custom domain. I then tried to access the custom domain using https. Then I started getting these errors. not sure if related. but i logged into the console using https://developers.backendless.com and now seems to be working.
