I have had a custom application written to search and display using the API, but since this has happened, I have been unable to edit custom fields in the contacts.
I have checked that I can edit the standard fields fine,, I have tried rolling back the database and files to before the changes, I have cleared cache, I have updated CiviCRM and Wordpress. BUT the issue remains.
I work for a charity and this is their support system for helping their members. Any experts have any Ideas. At this point I am willing to try anything you can think of.
