Pre_get_posts filter causes menu items to disappear

Hi,

I have created a filter to filter posts, on the archive page in this case. I’m using pre_get_posts and the results are fine. There’s only one problem: if a filter is used, the menu doesn’t load anymore. It’s very strange and I don’t know where to look anymore.

This is the filter:

add_action('pre_get_posts', 'wmw_custom_field_filter');
function wmw_custom_field_filter($query) {
	$tax_query = array('relation' => 'OR');
	$cat_set = false;
	if (isset($_GET['cat1'])) {
		$tax_query[] = array(
			'taxonomy' => 'category',
			'terms' => $_GET['cat1'],
			'field' => 'term_id',
		);
		$cat_set = true;
	}
	if (isset($_GET['cat2'])) {
		$tax_query[] = array(
			'taxonomy' => 'category',
			'terms' => $_GET['cat2'],
			'field' => 'term_id',
		);
		$cat_set = true;
	}
	if (isset($_GET['cat3'])) {
		$tax_query[] = array(
			'taxonomy' => 'category',
			'terms' => $_GET['cat3'],
			'field' => 'term_id',
		);
		$cat_set = true;
	} 
	if (isset($_GET['cat4'])) {
		$tax_query[] = array(
			'taxonomy' => 'category',
			'terms' => $_GET['cat4'],
			'field' => 'term_id',
		);
		$cat_set = true;
	}

	if ($cat_set) $query->set('tax_query', $tax_query);
        
        	if (isset($_GET['value'])) {
		$meta_query = array(
			array(
				'key' => '_wmw_mbe_age',
				'value' => $_GET['value'],
                                'compare' => LIKE,
			),
		);
		$query->set('meta_query', $meta_query);
	}        
	return $query;
        
}

Also when I add parameters to the url manually, the results are okay, but again the menu-items are gone. In fact the whole div with the menu items are gone (.menu-top-menu-container). So it looks like the query stops something else from being executed.

Hope someone knows what’s going wrong.

Thanks!
