validation_errors() returning an empty string after upgrading to 2.1.0

[quote author="mcryan" date="1329694016"]I've tried this on 2 instances of CI 2.1.0, one downloaded from the website, the other pulled from the stable branch on GitHub, both return an empty string when form validation fails.

Initially I noticed this on my own forms, then used the form validation example in the user guides and the outcome is the smae: <?php echo validation_errors(); ?> does not output anything.

I have tried this on PHP 5.2 and 5.3 on different servers, but the same problem is happening.

Any advice?[/quote]

I am using it just fine. There must be something else wrong in your code. Maybe shoe some code so we can see whats wrong.
