[Loris-dev] Blank white page

Mon Nov 6 13:51:26 EST 2017

Hi Alfredo,

It sounds like your file system permissions are preventing config.xml file
from being read, as they prevented writing to it during installation.

If you reset the ownership on your (new) loris root path:
 sudo chown -R lorisadmin.lorisadmin /var/www/loris

and then verify and restart your apache configuration steps
<https://github.com/aces/Loris/wiki/Installing-Loris-in-Depth#configuring-apache2>,
does that help?

If not, can you run and send the output of this command:
> ls -l /var/www/loris/project/

Best,
Christine
