Share button misplaced on Custom Theme

I’m trying to embed a social sharing plugin on my WordPress theme. However, when i use the plugin they appear at the bottom of the page after the footer. I have no idea what’s going on. Can anybody tell me how we can make these plugin’s icon appear at the bottom of the posts? I have used the plugin’s configurations to place it after posts but it goes to the bottom of the page regardless. Help needed desperately!
