Great thank you so much! Very helpful!
Thanks Joy. Turns out it was not a theme issue, but just a simple settings fix. For anyone else with this issue:
The comments will show up depending on your WordPress comments settings. Try going to Settings > Discussion and see if you have checked the option called “Automatically close comments on articles older than XX days
Sorry Joy, I use smush to compress image size when I upload them — do you recommend something else?
Do you know why it would work on some posts rather than others? Should I contact the maker of the theme? I have never had comments disabled so all of my posts should have had a comment box from when I published them
Please let me know how to fix this. Thanks!
