Source citations not working

Question

Although I have the following Sources <references /> tag at the bottom, my sources aren't displaying on the page. I've tried different formatting, but nothing seems to work for me.

Comments

As the page is "Public" we cannot see the source codes to help.

Have you closed all your starting <ref> tags with the required </ref> tags?

Do you have a Sources header above your <references /> tag?

Should I change the privacy settings? And what should I change them to?

I restored the changes I made and now it's all good.
