I'm trying to attach Meta Tags (Facebook Open Graph) for a page on the site. I have attached the Meta tags under Page Header Tags in SEO Section of Advanced Settings of Page. Despite this, I'm not seeing the Title, Description and image we have attached in these tags on https://developers.facebook.com/tools/debug/sharing. It gives a 302 response. Link Preview says Object Moved and Description is empty even though I have put the text into og:description meta tag. Is there any reason why Facebook is not using the Meta Tags from DNN Page Header Tags? How should I fix this?
