Facebook developer tool throw: Curl Error : OPERATION_TIMEOUTED Operation timed out after 10000 milliseconds with 0 out of -1 bytes received

Question

I am the admin of wordpress blog and i cannot publish the posts in Facebook with thumbnails. This problem only appear with the posts, so I can link homepage and static pages. When I use the Facebook Open Graph Debugger in homepage or static pages i get correct data and Facebook can read all og tags, but when i use it with any post I get that:

"Could not retrieve data from URL" "Curl Error : OPERATION_TIMEOUTED Operation timed out after 10000 milliseconds with 0 out of -1 bytes received"

Here are examples:

Correct: http://www.diversionerotica.com/

Wrong: http://www.diversionerotica.com/dia-del-padre-regala-una-sesion-de-fotos-erotica/

Any ideas?

Thanks.

Sorry if it's few information, but i cannot debug any post. Every error or warning in homepage was solved. I have tried to make all changes I found searching in google and stackoverflow but the problem wasn't solved.

Answer 1

Sorry, this problem wasn't related with Open Graph Tags. I was very confused because there were not enough information from Facebook about that. I thought that there was a problem in my code and Facebook debugger couldn't read the Open Graph Tags, but the problem was really that my server spent a lot of time to response the requests, and then Facebook Debugger threw a Timeout.

I was so confused because the response of homepage and static pages were correct, and the problem happened only with posts pages.

This problem was solved using a plugin for caching post pages. In this case I am using "WP Super Cache" plugin. Now the response of post pages is about 2 second, and Facebook Debugger can analyse Open Graph Tags correctly.
