This is the error I get when I do this Advanced:
URL https://www.thepopulistblog.com: Could not find Payload in comment form. Your theme is likely not compatible. Make sure you used a URL that contains your blog’s comment form, try again and, if still getting this result, please refer to SK2’s documentation.
Temporarily disabling form payload check.
But I checked the Comments.php and the needed hook is there… what am I missing here?
