In my PHP Codeigniter app focused on movie streaming, I want to add Facebook sharing feature.
I have these the most important og: tags (according to Facebook) enclosed in head tag:
og:imageog:titleog:description
However, if I want to share this website, Facebook doesn’t recognize any tags. Output from Facebook debugger looks like this: 
What could be the problem? I don’t even know, what to try to fix this issue. You can take look at my website here.
>Solution :
The problem is, that your site is hidden behind login and we, nor Facebook can access it without logging in.
When I access the URL you provided, I am redirected to login page, because "Watching series and movies is only for registered users". Facebook is therefore redirected too. And even though your movie page has OG tags, your login and signup pages don’t.
Facebook can’t access the page with OG tags.
You can allow access to movie pages to anonymous users, but disallow them from playing the movie unless they login.
