Read More Tag doesn't appear

I tested the Coller theme and the read more tag is working for me. Make sure you’re viewing the post on an archive page such as “/category/uncategorized/” as the read more functionality only works there, not on single post pages.

Hi Justin,
Thanks for your help. Yes, I have just checked all the posts in the archives, and the more tag is still not appearing. Does it matter that I am using a child theme?My links within posts are also not appear on archive or home page (anywhere that just contains a section of the full post)
My site is: https://greenbyblue.com

what are the edits in your child theme?
are you using a plugin for the excerpts?

please continue with your original topic in the theme’s forum;
