When adding a new individual with a current employer we are getting the following error:
Call to undefined method CRM_Contact_BAO_Relationship::legacyCreateMultiple()
The individual contact is created but no link to the employer. If we try to add the current employer on the contact summary screen we get the following:
Network Error Unable to reach the server. Please refresh this page in your browser and try again.
We can add the relationship under the relationship tab.
We upgraded CiviCRM to 5.61.4 from 5.58.1 and cleared the cache. No change after that. There is nothing in the PHP logs of the CiviCRM logs. Behavior seems to be unique to this site. Nothing has changed recently.
WordPress site running Version 6.2.2
Thanks in advance for any thoughts.
