I have a problem on random URLs hit on Faceboook account.
After posting a note on http://www.soycarmin.com/, generated a short url with 'google url shortener' and then stick it on the wall account https://www.facebook.com/pages/Soy-Carmín/1394963147496673
The problem I have is that occasionally brings this url 404.
If the url income I get from goo.gl, it directs me to the site properly ''m carmine' and if I look at the fields 'open graph' these are correctly added.
This causes occasionally have to be debugged my url to share properly.
Could someone help me with this situation?
