Share your site
In order for the visitors to share your site, you need to activate the share button under Settings tab >> Settings >> Social Media. In the section Share, click on On. There you can submit the Facebook url to like and a Facebook Share image.
If the field "Facebook URL to like" is filled with a Facebook page link, when sharing on Facebook, the post will share the Facebook page instead of the website.
When both Links and Share are enabled, a share icon will display after the other social media icons.
