SOLVED - No upload or files on web - mobile ok

I've installed the latest Owncloud 9.1.1 (stable) and there is no upload button or no files (even the example ones) on the web. Via the iphone app it all looks ok - and I can upload there no problem. Just the web is not there.

Please provide logfiles

I managed to find and fix the error - it was related to some security settings I had in Apache to make the apache server less susceptible to attacks.

By removing:
Header set Content-Security-Policy "script-src 'self'; object-src 'self'"

from the apache conf - the software worked as advertised
