Fix Social Media Sharing Features of Website

My friend owns the custom/php website [login to view URL], her freelancer account is at https://www.freelancer.com/u/taftchristina We need the social media sharing feature to work, it does not currently on most computers/phones tried. We need it to be working on every page and post, including the homepage. It needs to be displayed near the top of posts. And there are already icons which show how many times a post has been liked or commented on (as shown in the picture attached here). We would like an extra icon added to those icons to also indicate how many times a post has been shared on social media. (picture of the icons location attached) That social media sharing should include Twitter, Facebook, Whatsapp and Email. On Facebook, Twitter and Whatsapp the sharing feature should automatically include a picture on what is shared and follow a format indication of the following nature: Post Title by Author | Stories | Psych Victims And the same for every category eg. Post Title by Author | Article | Psych Victims Post Title | Location Date Time | Events | Psych Victims Post Title | Videos | Psych Victims Post Title by Author | News | Psych Victims Post Title | Discussions | Psych Victims Post Title | Research | Psych Victims Can you do this? Let me know. Thank You Daryl
