I upgraded to 2.0.15 and the entire system started displaying error messages for every report. So I reloaded the old version of 2.0.14 and everything appeared to work again. Except that it doesn't.
A new field has appeared among the list of user data. It is called "alias" with the title "YOUR_PROFILE_URL". It is a system field so I can't edit or unpublish it.
If I try to edit the details of any user in the database I now get an error when I try to save, because of this field.
Please can you advise urgently how I should fix this problem.
