I'm trying to visualize a contact (organization) and I'm receiving the following warning in the "Communication preferences" section.
Warning: Undefined array key "email_greeting_display" in /bitnami/wordpress/wp-content/uploads/civicrm/templates_c/es_MX/%%77/77A/77AF58B9%%CommunicationPreferences.tpl.php on line 53
However, this does not influence when updating the data and does not cause me major problems.
I've completely removed any trace of
define('WP_DEBUG', true); in the wp-config.php file
