Body

I have a site hosted on github pages: https://www.nuttyskitchen.co.uk and have been successfully sharing pages on facebook until today. Now all of a sudden the facebook sharing debugger facebook sharing debugger is receiving a 403 'Bad Response Code' from the site and any pages I try to check, including those that previously had a HTTP/1.1 200 OK response. Now when I try to share any page on FB, the image that is supposed to be displayed is blank because of this.

I ran a cURL command to see what was going on (but I have to admit, unless it says status HTTP/1.1 200 OK) I'm pretty lost as to what everything else means. This is the response from that cURL command:

C:\Users\owner>curl -I nuttyskitchen.co.uk
HTTP/1.1 301 Moved Permanently
Connection: keep-alive
Content-Length: 162

and it's this line HTTP/1.1 301 Moved Permanently that has me concerned that something is wrong because if I check example.com I get this response:

C:\Users\owner>curl -I example.com

As you can see I get HTTP/1.1 200 OK which is what I would expect from nuttyskitchen.co.uk

Can anyone tell me what has happened to cause this problem?

Thanks in advance,

Hi there @LiteBrite82,

I don't think this is programming related, but more to do with the http response from githhub pages server. The problem is, I was successfully sharing content from the site with facebook, but now it is broken. When I try to share a URL on facebook the images that should appear don't and when I look in facebooks' sharing debugger, it is receiving a 403 'Bad Response' from the github pages server, instead of a HTTP status 200 OK. Having checked out the server response using cURL, I can see that there appears to be a problem with the response from my site hosted on github pages. This includes all other pages that were 200 OK up until today.

So, my question is, has something happened to the github pages server today? Not sure where to post that question!

Today things are somewhat resolved in as much as the links I share on facebook do have the images that they are supposed to have. The only thing that is still a little amiss is the http response that facebooks sharing debugger is receiving which is a 206 'partial' so I don't know whether the fault lies with facebook or the github pages server???
