The site is http://services.bg/

I am testing the Social Meta tag and there is something weird.
Facebook is not fetching image.

but .. http://smo.knowem.com/ is showing and fetching image.

When you open site info it shows OG tags and image path.
When you type image path into browser, it gives 404.

I have not edited .htaccess. They are as by install default.
So where could be the problem?
I see in .htaccess everthing is redirected to index.php
Tried to disable those redirects, but still no go!?
