Whenever I try to comment on a post on my website it leads me to a wp-comments-post.php page, which says “Bummer – we couldnt find what you’re looking for etc etc”
I am running SSL on my website, doing some research it seems this might be an issue with the theme not supporting HTTPS? Is this true?
You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
