Duplicate meta tags and short tags

When i check webmaster tools I keep getting the following errors.

Duplicate meta descriptions
Duplicate title tags
Short meta descpritions

Does anyone know how I would go about fixing these things? Any help is appreciated.

I too face the same problem, any help would be appreciated

Do you have your showpost pages still enabled?

How do I know if I have them enabled? I looked in vbseo I dont see any settings for that

If you have the permalink replacing the showpost option and have the showpost.php file excluded in your robots file then it is pretty much disabled.
