Add sidebar.

Hey all. this is my first post so im not 100% sure if this is the good forum.

The problem i have is in http://www.pablogeo.com – i’m using Ultimate Tag Warrior but when i click on a tag i dont have any sidebar.

Code of my theme to show the sidebar is:
<?php /* If this is the frontpage */ if ( is_home() || is_search() ||is_404() ||is_archive() ||is_page() ) { ?> <!–Begin Home, Search, etc. Page Sidebar –>

which i tried adding index.php but i get double sidebars. i just need to add the normal sidebar to index.php?tag=X

any ideas?
