I did not find the files mentioned in the fix in the All Business template. Here are the files:
- /includes/templates/YOUR_TEMPLATE/templates/tpl_login_default.php
- /includes/templates/YOUR_TEMPLATE/templates/tpl_timeout_default.php

Do I need to make a copy of them from the default template and put them in all business?

Thanks for your help.
I did not modify these files so they are not in the template package. Please see this article:
