Workaround

Please, make sure of having a full site backup of your site before proceeding.

• Open …/wp-content/plugins/wp-event-manager-registrations/wp-event-manager-registrations-functions.php file.
• Look for line 497.
• Replace:

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

  if(!function_exists('get_event_registration_count')) {     /**      * Get number of registrations for a event      * @param  int $event_id      * @return int      */     function get_event_registration_count($event_id) {         return sizeof(get_posts(array(             'post_type'      => 'event_registration',             'post_status'    => array_merge(array_keys(get_event_registration_statuses()), array('publish')),             'posts_per_page' => -1,             'fields'         => 'ids',             'post_parent'    => $event_id         )));     } }

• With:

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

  if(!function_exists('get_event_registration_count')) {     /**      * Get number of registrations for a event      * @param  int $event_id      * @return int      */     function get_event_registration_count($event_id) {                   // WPML workaround for compsupp-7562 - Part I         $translations = apply_filters( 'wpml_get_element_translations', null, $event_id, 'post_' . get_post_type($event_id) );                   // Extract the IDs of the translated posts         $event_ids = array_map(function($translation) {             return $translation->element_id;         }, $translations);               // Get event registrations for all translations         return sizeof(get_posts(array(             'post_type'      => 'event_registration',             'post_status'    => array_merge(array_keys(get_event_registration_statuses()), array('publish')),             'posts_per_page' => -1,             'fields'         => 'ids',             'post_parent__in' => $event_ids // Get all registrations for the event IDs         )));     }       }

• Then, look for line 595.
• Replace:

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

  if(!function_exists('user_has_registered_for_event')) {     /**      * See if a user has already appled for a event      * @param  int $user_id, $event_id      * @return int      */     function user_has_registered_for_event($user_id, $event_id) {         if(!$user_id) {             return false;         }         return sizeof(get_posts(array(             'post_type'      => 'event_registration',             'post_status'    => array_merge(array_keys(get_event_registration_statuses()), array('publish')),             'posts_per_page' => 1,             'fields'         => 'ids',             'post_parent'    => $event_id,             'meta_query'     => array(                 array(                     'key' => '_attendee_user_id',                     'value' => absint($user_id)                 )             )         )));     } }
