The theme provides maintenance page templates:
- maintenance-page-tpl.php: This page template is used when the site has been set offline by the administrator.
- maintenance-page--offline.tpl.php: This page template is used when the site cannot get in contact with the database.
It is common for ding2 sites to have the DDBasic theme reside in the folder /profiles/ding2/themes/ddbasic. In this case, you will need to add the following lines to your settings.php file in order for both template files to be displayed properly:
$conf['install_profile'] = 'ding2';
$conf['maintenance_theme'] = 'ddbasic';
