You’re welcome @bambam944! 🙂
Yeap, I had the exactly same problem here. I temporarily fixed it locally by changing line #63 in functions.php from:
add_filter( 'comments_popup_link_attributes', function() { return ' itemprop="discussionUrl"'; } ); # schema.org property on comments links
to
add_filter( 'comments_popup_link_attributes', "return ' itemprop=\"discussionUrl\"';" ); # schema.org property on comments links
