[SOLVED ]Zoneminder video is there, permission problem for events, Ubuntu

[jrf]

Done:
- Ubuntu LTS 12.04 updated to LTS 14.04
Result:
- Zoneminder 1.28.1 (2 IP cameras, 3 in total zones) not working anymore

Actions:
- Several steps taken from Wiki, removed and installed several programs (LAMP, zoneminder), did setups.
I have the video running, but in three zones defined I cannot see pictures in the zone definition area. Zones are defined based on my screenshots of the earlier installation. But zones defined as before (MODECT).
In the ZM Console the Souce is colored ORANGE? The cycle and motage option is working. Videostream is visible.
But I am not recording any events, the LOG is all red, because of permissions. Help possible? Logfile part attached:

If I look at the LOG file there are a lot of lines that say: "Permission denied".
Is anyone able to tell me which permission I have to set where?

[jrf]

After some searches I found out that the permission to the zoneminder directory was missing.

Changes made in terminal:
sudo su
service zoneminder stop
chown -R www-data:www-data /var/cache/zoneminder

Result:
Working installation Ubuntu 14.04 - Zoneminder 1.28.1
