So you have just finished installing the Squible Wordpress theme and you keep getting the following error when using the tags or comments feature:

 Fatal error: Call to undefined function: show_tags() in #######/wp-content/themes/squible/single.php on line 153

The easiest way to fix this issue is to install the Ultimate Tag Warrior plugin for Wordpress.  You can find it at http://www.neato.co.nz/ultimate-tag-warrior/
