1. I am using the grid layout for blog posts on the homepage but the author avatars don’t show. Is there a way to make them appear?
I don’t think there is author avatar built into grid layout. You will need to contact us for this customization.
For some reason in this layout it only shows 6 posts on the homepage so now there is a big white gap before the end of the page. I went in the settings and choose to show more than 6 but it’s not working.
How is your homepage setup? is it by using a static page and blog shortcode? or default which is showing your latest posts?
If blog shortcode, you need to change the number_posts attribute. If it’s your latest post, the setting is in Settings -> Reading -> Blog pages show at most
