i see your website footer area is missing. So one of your plugin is creating issue which making your website incomplete. Please check which of your newly added plugin output incomplete website. You can disable and see if website footer area is back and enable one by one to find which one creating issue.
Let me know.
I have done some changes to this plugin. Now check.
Please do not update this plugin. If you update then this changes will be gone.
Also your website missing footer area, so most of the plugin which add script in your website will not work. You may not understand this now, but that missing footer area will have very strong impact in your website. It is a wordpress requirement that every theme must have header and footer (it is not visual header and footer, but some code). So your theme may have but may some poorly coded plugin may remove that.
