Good evening Vivianne and welcome back!
Thank you for reaching out to us.
I would love to help you with this topic.
But first, can you confirm if you have :
- Used both of Barry’s snippets ?
- Changed the setting in Events > Settings > Display to Default Page template ?
Could you also share an example URL where you have the comments enabled, so that I can take a look at it ?
Finally, it might be a simple matter of tweaking the snippets to add the proper syntax to get the comment counts as explained here: https://codex.wordpress.org/Function_Reference/comments_number
Best regards,
Geoff B.
