I tried to read PR 10905.
It is way too complicated, too many voices, I don’t understand that.
I will follow your steps and I tell you the results here.
Thanks

As I said before this is still NOT RESOLVED.

My last input declared the fault was in my child theme, is true, but is not clear why.

My child theme has loads of functions, so I started to disable the ACTIONS one by by one, in order to find the faulty function. I find it. I shared with the theme developer. He sees no problem. Now I going to share this function here:

// Indigo Adjust Main Queries
add_action( 'pre_get_posts', 'indigo_adjust_queries' );
function indigo_adjust_queries( $query ) {
	if ( !is_admin() && is_post_type_archive( 'actividade' ) && $query->is_main_query() ) :
		$query->set( 'post_per_page', -1 );
		$query->set( 'orderby', 'post_modified' );
		$query->set( 'order', 'DESC' );
	endif; // actividade

	if ( !is_admin() && is_post_type_archive( 'colaborador' ) && $query->is_main_query() ) :
		$query->set( 'post_per_page', -1 );
		$query->set( 'orderby', array(
			'relation' => 'AND',
			array(
				'orderby' => 'menu_order',
				'order', 'ASC'
			),
			array(
				'orderby' => 'post_title',
				'order', 'ASC'
			)
		));
	endif; // colaborador

	if ( !is_admin() && is_post_type_archive( 'evento' ) && $query->is_main_query() ) :
    $today = date('Ymd');
		$query->set( 'post_per_page', -1 );
		$query->set( 'post_type', 'evento' );
    $query->set( 'meta_key', 'data_do_evento' );
    $query->set( 'orderby', 'meta_value_num' );
    $query->set( 'order', 'ASC' );
    $query->set( 'meta_query', array(
      array(
        'key' => 'data_do_evento',
        'compare' => '>=',
        'value' => $today,
        'type' => 'numeric'
      )
    ));
	endif; // evento

	if ( !is_admin() && is_post_type_archive( 'course' ) && $query->is_main_query() ) :
		$query->set( 'post_per_page', -1 );
		$query->set( 'orderby', 'post_modified' );
		$query->set( 'order', 'DESC' );
	endif; // course

	$term = single_term_title( '', false );
	if ( $term ) :
		if ( !is_admin() && is_tax( 'grupo' ) && $query->is_main_query() ) :
			$query->set( 'post_per_page', -1 );
			$query->set( 'post_type', 'colaborador' );
			$query->set( 'orderby', 'menu_order' );
			$query->set( 'order', 'ASC' );
			$query->set( 'tax_query', array(
				array(
					'taxonomy' => 'grupo',
					'field' => 'name',
					'operator' => 'IN',
					'terms' => $term
				)
			));
		endif; // colaborador

		if ( !is_admin() && is_tax( 'tipo' ) && $query->is_main_query() ) :
			$query->set( 'post_per_page', -1 );
			$query->set( 'post_type', 'actividade' );
			$query->set( 'orderby', 'post_modified' );
			$query->set( 'order', 'DESC' );
			$query->set( 'tax_query', array(
				array(
					'taxonomy' => 'tipo',
					'field' => 'name',
					'operator' => 'IN',
					'terms' => $term
				)
			));
		endif; // actividade
	endif; // terms

} // END indigo_adjust_queries

Here, again, I went disabling sections, one at the time, to find the faulty part. This single line is the one causing the problem:

$term = single_term_title( '', false );

I really don’t see any problem with this, my developer either, can you explain it? Or better get a fix for it…

Thanks
Alain

Hi

I tried to replace: $term = single_term_title( '', false );
with $term = $query->query_vars['term'];
it gave me HUGE amount of errors everywhere.

Undefined index: term

I don’t see any documentation declaring errors or a different usage here: https://developer.wordpress.org/reference/functions/single_term_title/

Thanks

HI Saša

Thank you very much for your support… Your solution is working fine, I have not tested online yet, only local, but the error is gone.

$query->set( 'tax_query',... has to do with using single_term_title... seems to me, that using query_vars['term'] creates a different situation.

The idea was to find out which ‘grupo’ (group) was been displayed.

Thanks
Alain
