Insert Read More tag not showing up

I am trying to set up a post with a summary and then to insert a Read More tag, which is showing up in the body of the text AND in text mode like this: <!–more keep reading–>

BUT when I update and save the post it does not show up on my site. I’ve attached the link to the site which shows no “keep reading” tag. It should appear after the end of the last sentence.

I’ve played around with my themes customizable options with colours of the hover etc. as well as the discussion settings which is set to Summary.

I’m out of ideas. Please advise!
