KNOWS (blog) as a Custom Webapp possible?

I uploaded the files from in a directory kn created by the
Yunohost-Application "Custom Web"with mysql.
Starting mysite/kn/warmup shows one error in the php-setting (“Apache mod_rewrite, We couldnt detect if mod_rewrite was installed. Known cannot process page URLs without it. Proceed with caution.”)
When proceeding I could enter the definition for the database, I accepted the field with a directory for uploads under www.
After this “installation"nothing” appears, when I call the app once more. Any help? Perhaps only a few settings?

The problem is probably that Yunohost use Nginx and your apps is waiting for Apache. You need to modifiy php settings. How? I don’t know yet. Hope this will help to make someone answer you with a better response.
