I just installed OMV5 to have a look at it. I used the 5.0.5 iso, updated everything and installed OMV Extras. Then I tried to enable SSL but got the message "An error has occured". But the service seems to be activated. I can connect via https now but the whole systems information tab remains blank. Everything else seems to be working so far. When I connect via http it's fine.
In the system log there is only some reports about postfix and monit says "alert handler failed"
Anyone here who experienced the same behavior?
