I’ve switched to Twenty Ten and the plugin works fine so it would appear that there is something wrong with my theme. Is there anything that needs to be included to allow plugins?
At the moment in page.php to display the content I have:
<?php the_content(); ?>
This was one of the ones I found previously. I need more functionallity than the one you have linked.
