Metatag won't work for homepage? The Metatag Module inputs (Such as Description, Abstract, ETC, and that includes Page Title) won't trigger on the home page.

I already read in a forum thread that didn't give an in-program solution. I assume it's a solved problem, because it affects almost any site.

How can one solve it?

  Check if you have the code for the main content on the homepage .tpl file:
  
  &lt;?php print render($page['content']); ?&gt;
