How to insert social share button in header

Hi there,

you would need to add a Social Sharing plugin like GP Social Share.

https://wordpress.org/plugins/gp-social-share-svg/

You can disable its auto placement using a GP hook in its settings and the FAQ in the above link provides a shortcode you could add to your header element

I have downloaded the plugin..

This is the current code in my page hero

<h1>{{post_title}}</h1>
[page_hero_gravatar] {{post_author}} | {{post_date}}

what should i do next

This shortcode needs to be added: [gp-social]
