       Good morning.With the latest updated versions.
   
       I have with this module multiple very annoying and worrying warnings.
   
       example on the back-office in the profile of a user account:
   
       Warning: Undefined array key "admin_form" in /…./public_html/monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user-password.php online 64
   
       If I update the profile:
   
       Warning: Undefined array key "_acf_user" in /…./monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user-password.php on line 106
   
       Warning: Cannot modify header information - headers already sent by (output started at /…./monsite.fr/aece-pre.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields /user/class-user-password.php:106) in /home/sc3sid10/public_html/aece-pre.fr/wp-includes/pluggable.php on line 1427
   
       Warning: Cannot modify header information - headers already sent by (output started at /…./monsite.fr/wp-content/plugins/acf-frontend-form-element/main/frontend/fields/user/class-user -password.php:106) in /home/sc3sid10/public_html/aece-pre.fr/wp-includes/pluggable.php on line 1430
   
       If I refresh the page it gives me this:
   
       Invalid account ID.
   
       Any idea please?
   
       I have the ACF PRO plugin etc…
   
       At your service for more details.
