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 :
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 !
