This is what I received when I tried a test run:
Error:Protocol https not supported or disabled in libcurl Valid app_id ERROR:Protocol https not supported or disabled in libcurl
This is what's showing in history for all facebook posts:
-=ERROR=- Protocol https not supported or disabled in libcurl
Any idea what could be causing this all of a sudden?

Hi
This error means that cURL is misconfigured on your server. Please contact your hosting provider and ask them to fix this.
Unlike Twitter or Google+ that could be automatically switched to non-SSL connections in such cases, Facebook requires to be accessed by SSL (https) at all times.
What is was is I had replaced CurlSSL on my server with Curl. I went back to CurlSSL and all is fine.
This is what I received when I tried a test run:
Valid app_id ERROR:couldn't connect to host
Any idea what could be causing this all of a sudden?
You need to contact your hosting provider.
"couldn't connect to host" means your server can't find remote website (in your case facebook.com). It's either DNS is broken or outgoing connections are disabled. Anyway your hoster need to take a look at this.
