We're on 4.6.8 and having an issue where when saving an activity which is assigned to a contact the following error is displayed:
Sorry but we are not able to provide this at the moment.
Sorry an Error Occured MysqlColumnNameOrAlias is not a recognised (camel cased) data type.
If it is not assigned to anyone there is no error. However, if you click back and go into the record again the activity has in fact been saved. Not a massive issue as the activity is saved but it's not good from a usability perspective.
From looking online it looks like the following code is where the error is being generated from:
https://github.com/civicrm/civicrm-core/blob/master/CRM/Utils/Type.php
Any ideas what is causing this?
