I hope you are well today and thank you for your question.
I have tested it on my test site using HTTPS and it’s working fine for me using latest version of Pinbin theme.
This can be child theme issue on your site so to confirm it just temporary use the Pinbin theme instead of child theme on your site. If everything works fine then it’s your child theme issue so just share me your child theme so that i can troubleshoot it.
Thanks for your help. I was able to find the root cause of the problem. When I migrated to SSL, I installed a plugin called “WP Force SSL”. What this plugin did was to change the single.php file of my theme. It added a function called makeClickableLinks that was causing an error in the server, so everything stopped after calling it. Even when I inactivated it, the code was left there.
So I removed the plugin and ran a SQL in my database to change all http references to https and now everything is back to normal.
The reason why I created a child theme was to translate some texts into Spanish and made few modifications of design.
