No Webgui after update 1.0.x->1.0.21

I had a running install of OMV, but after updating from 1.0.17/18/19 to 1.0.21 i got no access to the webgui any more.
The webgui give me a empty page (incl source).

/var/log/nginx/openmediavault-webgui_access.log

php5-fpm shows no errors (also running) nothing at dmesg ....
omv-firstaid - webgui - wont help (changed port for test, it works but also a empty page)

for some reason /var/log/nginx/openmediavault-webgui_error.log is not generated any more (_access.log is working)
last entry is this

reboot, update ... already tried, all services are working like a charm besides the webgui (nothing installed what would fetch the :80 web)

any suggestions ?

# omv-mkconf nginx
# omv-mkconf php5fpm

done, reboot (to be safe) nothing changed

NAS:~# omv-engined -d -f

fixed it,
I installed omv in a vm and copied the /etc/php5-fpm/ folder to the NAS, reboot -> everything is working.

I never changed anything at this configs, maybe there is/was an upgrade problem.
