I found
this recent ticket with a similar problem. The process to fix it was:
- Disable GeoBlock
- Afterwards you must remember to force Facebook to purge its cache. Otherwise you will keep seeing the old (blocked) page. You can do that at https://developers.facebook.com/tools/debug/
If this doesn't help, please paste me the URL of the article. Perhaps there's a tmpl or template keyword that's being blocked? Also, are you using any third party plugin to implement AMP (accelerated mobile pages) or Facebook's Instant Articles on your site?
