I installed SEO by Yoast and added in some info in my post. I went to the top right area and clicked on "check" next to "SEO." When I did that, I got this error:
Your hosting environment does not support PHP's Document Object Model. To enjoy all the benefits of the page analysis feature, you'll need to (get your host to) install it.
So I contacted my host (Rackspace) and they said the error is too vague and once I have more information they can look into it and help me. I have no idea where to look for more information.
Please help.
