Mout, I found some solution before fixing this bug in next version of the plugin.
You must to add to functions.php this code:
<?php
add_action( 'parse_query', 'tribe_fix_tag_query' );
function tribe_fix_tag_query( $query ) {
if ( $query->is_tag && (array) $query->get( 'post_type' ) != array( TribeEvents::POSTTYPE ) ) {
if ( empty( $query->query_vars['post_type'] ) ) {
$query->query_vars['post_type'] = array( 'post' );
}
if ( ! ( $query->query_vars['post_type'] == array( 'post' ) || $query->query_vars == 'post' ) ) {
remove_action( 'parse_query', array( 'TribeEventsQuery', 'parse_query' ), 50 );
remove_action( 'pre_get_posts', array( 'TribeEventsQuery', 'pre_get_posts' ), 50 );
}
}
}
