wp_dropdown_categories with custom taxo goes to 404

    I have tried a couple solutions to get a dropdown of custom taxonomy terms that link to entries with the selected term.

    I have tried a number of solutions I found in the codex and forums, shown below, and keep getting 404s as the results pages when the link resolves. 

    <form id="category-select" class="category-select" action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get">

		<?php
		$args = array(
                        'taxonomy' => 'location',
                        'show_option_none' => __( 'Select category' ),
			'show_count'       => 1,
			'orderby'          => 'name',
			'echo'             => 0,
		);
		?>

		<?php $select  = wp_dropdown_categories( $args ); ?>
		<?php $replace = "<select$1 onchange='return this.form.submit()'>"; ?>
		<?php $select  = preg_replace( '#<select([^>]*)>#', $replace, $select ); ?>

		<?php echo $select; ?>

		<noscript>
			<input type="submit" value="View" />
		</noscript>

	</form>
    <?php wp_dropdown_categories('taxonomy=location&show_option_none=Select location'); ?>

<script type="text/javascript"><!--
    var dropdown = document.getElementById("cat");
    function onCatChange() {
		if ( dropdown.options[dropdown.selectedIndex].value > 0 ) {
			location.href = "<?php echo get_option('home');
?>/?cat="+dropdown.options[dropdown.selectedIndex].value;
		}
    }
    dropdown.onchange = onCatChange;
--></script>
    <form id="category-select" class="category-select" action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get">
    <?php wp_dropdown_categories( 'taxonomy=location&show_option_none=Select location' ); ?>
    <input type="submit" name="submit" value="view" />
</form>

    I deactivate all plugins except the custom plugin with the CPT and taxonomies. I set permalinks to plain and back to pretty. I tested with the Twenty Fifteen theme. All had the same result, 404.

    How can I fix this?

    Sadly wp_dropdown_categories seems broken when it comes to the permalinks.

    I’m using this working version from here. 

    <form action="<?php bloginfo('url'); ?>/" method="get">

<?php
$term_id = 279;
$taxonomy_name = 'categories';
$termchildren = get_term_children( $term_id, $taxonomy_name );
$children = array();
foreach ($termchildren as $child) {
  $term = get_term_by( 'id', $child, $taxonomy_name );
  $children[$term->name] = $term;
}
ksort($children);
echo '<select name="' . $taxonomy_name . '" onchange="this.form.submit()">';
echo '<option selected>Branding...</option>';
foreach ( $children as $child ) {
  $term = get_term_by( 'id', $child->term_id, $taxonomy_name );
  echo '<option value="'. $term->slug .'">' . $term->name . '</a></option>';
}
echo '</select>';
?>
<noscript><div><input type="submit" value="View" /></div></noscript>

</form>

    Sadly wp_dropdown_catetories seems broken when it comes to permalinks.

    I am using a different method from here.
