Yes, even I am facing the same error. Initially, I thought that it might be because of the recent API Error. But it seems that API errors have been resolved still we are getting the internal server error.
Taking a close look at the error log shows following error
[proxy_fcgi:error [pid 13396:tid 140535473886976 [client 206.84.230.131:0 AH01071: Got error 'PHP message: [Cloudflare ERROR: [CLIENT API Array\n(\n [type => request\n [path => https://api.cloudflare.com............API Array\n(\n [type => response\n [reason => Internal Server Error\n [code => 500\n)\n PHP message: [Cloudflare ERROR: Internal Server Error ', referer: https://mysite.com/wp-admin/options-general.php?page=cloudflare
Okay so the problem might be on Cloudflares servers rather than on my server.
Yes, I have the same issue too.
RED : Internal Server Error.
