Update: My developer says there was a javascript error with the plugin:
gplus-comments/includes/lib/frontend.php
row 85:
echo ‘<script> jQuery(“#comment-tabs”).tabs();</script>’ . PHP_EOL;
Should be:
echo ‘<script>
(function(cash) {
$(function() {
jQuery(“#comment-tabs”).tabs();
});
})(jQuery);
</script>’ . PHP_EOL;
Now that we’ve got it working right, I love this plugin! Hope that error fix can help others 🙂
