Not working on Rowling theme

Hi,

I can’t get the plugin to work on Rowling theme (https://andersnoren.se/themes/rowling/)

I watched your video (https://benandjacq.com/wordpress-plugin-wp-old-post-date-remover/) and was able to remove the dates from both the homepage and individual posts entirely by using this:

.single-post .post-meta {
   display: none;
}
.post-meta {
   display: none;
}

Unfortunately that has also taken away the “X comments” part, too, and I’d prefer to use your plugin if you could possibly add the functionality?

Thanks.
