An updated purepro version will be available soon in the download area
for geeklog 1.7.0.
You can manualy change settings (layout, colors, menu...) in the default-settings.php file.
Purepro need to have write permission to the purepro/css folder.
Delete the purepro/css/my-site folder to rebuild css with new layout, color, menu... settings.
This is the default theme for geeklog.fr
I'm available to customise your themes or plugins for your Geeklog CMS
