Broken venue meta query

Hi,

I’ve been using Event Organiser for some time now and everything was working fine. I created a new venue meta data called “open” and I was using a php snippet to display the a list of all venues that were opened. Here is the working script:

<?php
$venue_query = array(
    array(
       'key' => '_open',
       'value' => '1'
    )
);
$venues = eo_get_venues( array( 'meta_query' => $venue_query ) );
if( $venues ){
    echo '<ul>'; 
    foreach($venues as $venue):
        $venue_id = (int) $venue->term_id;
        printf('<li> <a href="%s">%s</a>', eo_get_venue_link($venue_id), esc_html($venue->name));
    endforeach; 
    echo '</ul>';
 }
?>

This code was working perfectly until I’ve updated the plugin to the last available version. Now it is broken.

I tried the same script with an empty meta_query array, and it works fine so it as definitely something to do with the meta data.

Do you know what is going wrong with that query?

Thanks a lot for reading this message and maybe to answer it!
