if you are using tribe_events post type and facing 404 on single event view just use this code and past in functions.php
`function search_filter($query) {
if ( !is_admin() && $query->is_main_query() ) {
$query->set(‘post_type’, ‘tribe_events’);
}
}
$r=explode(“/”,$_SERVER[“REQUEST_URI”]);
if(in_array(‘event’, $r))
add_action(‘pre_get_posts’,’search_filter’);
