I am unable to make certain edits to CiviCRM; unable to edit certain records and unable to edit the visibility of groups.

I think the problem is this: Cannot add or update a child row: a foreign key constraint fails (`ea...")

The error message is referring to a group '58' which I deleted and replaced with group "62".

How do I find the exact problem and fix it?

I'm on WP 4.5.3 with CiviCRM 4.7.9.

Here is the error message:

Database Error Code: Cannot add or update a child row: a foreign key constraint fails (earthcha_civicrm.civicrm_group_contact, CONSTRAINT FK_civicrm_group_contact_group_id FOREIGN KEY (group_id) REFERENCES civicrm_group (id) ON DELETE CASCADE), 1452 Additional Details: Array ( [callback] => Array ( [0] => CRM_Core_Error [1] => handle )
