Subject: [Owncloud] Issue with blank screen

Hello, I was redirected to this email address after trying for a few weekt
to find a solution in the general owncloud forums. The problem Is a blank
screen when trying to access the web interface of my owncloud installation.
(clients also can not connect) I can not tell exactly what caused the
problem. I have tried reinstalling both version 4 and 5, and creating a
fresh database. I also find these errors in the log:

{"app":"PHP","message":"include(): Filename cannot be empty at
\/home\/jms\/owncloud\/lib\/template.php#441","level":2,"time":1369107865}
{"app":"PHP","message":"include(): Failed opening '' for inclusion
