Now that Civi version 4.7.25 has introduced creation_date for activities, I am having SQL errors when I try to create a new activity or delete a recent activity, which results in fatal errors:
Unknown column 'created_date' in 'field list'
I can't replicate this in the CiviCRM sandbox (http://dmaster.demo.civicrm.org/civicrm/), although that is running Civi 4.7.28.
If I run the SQL command in phpmyadmin, then it gives the same error, so I guess there's some problem with the table civicrm_activity since updating to 4.7.25
Any ideas?
