Google+ +1 Button Backend Error  

When you click on the +1 button above, I was getting a red exclaimation mark and I wasn't sure why.

Here are a few possible causes and solutions:

  1. The URL is not publicly available.
    • In order for the button to function correctly, the page must be available without requiring authentication.
  2. The HTTP Response was not a 200.
    • This was the cause of my troubles. I didn't realize that my page was returning a 404. I have since fixed the rewrite conditions in Apache to resolve this issue.
  3. Redirects.
    • Any redirecting of the user is not something that Google wants to +1.

I hope that helps!
