Problem with posting link from site on Facebook

I post links daily from my site daily when suddenly I cannot share my posts on facebook. When I do, I just see the url of my website. It does the same thing even with old posts.

These are the messages that i get when i try to debug using the facebook debugger

1. Critical Errors That Must Be Fixed
Could Not Follow Redirected – URL requested a HTTP redirect, but it could not be followed.

2. Warnings That Should Be Fixed
Inferred Property – The ‘og:url’ property should be explicitly provided, even if a value can be inferred from other tags.

3. Error parsing input URL, no data was cached, or no data was scraped.

Please help.

my website is http://www.thirdculture.cc
