Having Some Coding Problems

Hello,

I will sometimes have some coding errors on my page that I think are leading to strange redirects. Sometimes I get “page redirected too many times” errors. Other times, my post seems to render all right, but none of my Facebook likes are showing up at all. This page is an example:

https://www.bipolartoday.com/the-off-label-marketing-war-how-much-do-we-really-trust-our-physicians/

It has likes on my Facebook page, so I know it has likes. A friend also told me that it won’t render properly on an html editor.

Would someone please let me know what is going on with my code? It only seems to affect me sometimes, but I can’t figure out what is going wrong.
