What is 503 backend fetch failed whenshare wordpress post to facebook

once you wrote a wonderful post , add the social sharing plugin in wordpress , then you test to share your post to facebook ….. BOOM ! 503 backend fetch failed ? what the hell is this?

Well , now you wonder/complain that plugin installed , then you uninstall the plugin and install another one …. BOOM !! 503 again !

OK , remember , every time you get in trouble with facebook , go to facebook debug tool first :

https://developers.facebook.com/tools/debug/sharing/

input your page URL that got in trouble, press “debug” , ding-dong ! the answer is here .

For this example, it’s problem about og:image , to fix this , we recommand All in one SEO pack , you can find it in wordpress plugins .

then , go to [Feature Manager ] , active [Social Meta]

For most of situations , after setting correct og:image and go to faceboook debug page recap your post, will work.

But for me, unfortunately , no luck still. Sometimes ,it is jsut about time. Don’t know why facebook debug tool still get cache content. Just wait and retry . It will work finally .

Good luck !
