In the lib/config.php simple add the is_tax to the conditions array and then the name of the template to the second array like so,
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | array( 'is_404', 'is_front_page', 'is_tax'), /** * Page template checks (via is_page_template()) * Any of these page templates that return true won't show the sidebar */ array( .... .... 'taxonomy.php', 'taxonomy-{taxonomy_slug}-{taxonomy_value}.php' ) |
For a list of all the available conditional array values have a look here.
