[quote=“discodemons, post:1, topic:57074”]When opening my site in the browser and viewing the source code, all the required meta data is there, for both new and old blog posts. Obviously, my server is showing a different version of my site (or no version at all) to the Facebook crawler than it shows in the browser.
This problem came literally over night, I didn’t change anything in my WordPress or server configuration. Any help much appreciated, I’m pretty much at my wit’s end here with this!
Pay attention to the error messages and use a search engine.
Response Code: 503
Bad Response Code: URL returned a bad HTTP response code.
"10.5.4 503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
Note: The existence of the 503 status code does not imply that a
server must use it when becoming overloaded. Some servers may wish
to simply refuse the connection."
There is no mention of when or how often they atempted to access the URL, I suggest you check your access.log and error.log files in case this particular error is getting logged.
