total_tagged_posts causes an php-error when used in posts.php

[lucasdidthis]

Hej!

I really like your plugin. Generally speaking it works like a charm, but unfortunately I'm having some trouble:

I can't use total_tagged_posts in my posts.php, it always throws an php-error. :-(

Some help on how to fix this would be highly appreciated.
Btw.: I use Anchor version 0.12.7.

Thanks,
Lucas
