Can you change an event in that calendar?

I CAN modify existing event. But, i found a critical issue: i cannot add new event with iCalendar, BlackBerry 10 smartphone, even SOGo web interface. After saving a event with SOGo web, no event created at all.

Packages installed on my server (CentOS 6.7):

When creating event with SOGo web, sometimes it says:

EXCEPTION: <NSException: 0x56117eaeeea8> NAME:NSInvalidArgumentException REASON:Tried to add nil to array INFO:(null)
<0x0x56117c941278[WOWatchDogChild]> child 14935 exited
<0x0x56117c941278[WOWatchDogChild]> (terminated due to signal 6)
<0x0x56117c8cca98[WOWatchDog]> child spawned with pid 14936

If i create a new event with non-ascii characters (Chinese, in my case) and English, SOGo failed to save it with "Bad Gateway" error popup on top-right corner.

Server log has:

"Feb 22 22:39:17 sogod [15166]: [ERROR] <0x7CB98408[SOGoAppointmentFolder]:personal> DAV property '{}updated-by' has no matching SQL field, response could be incomplete"

I tried to reproduce the same issue, but seems it occurs randomly.

Forget those "DAV property" errors. They occur, because Apple decided to 'enhance' its own calDAV standard, without changing the standart itself.
They added 3 properties which are not present in any other implementation of the calDAV standard.
Those are:

As SOGo does not know them, they are ignored, which produces those error messages.

Which language do you use for your tests?
Does those errors also happen when using english?

English works fine most times, but i cannot remember whether it failed before.

Reproduced this issue today:

1) cannot create new calendar event (not task) with SOGo web UI (v3.0.1) with Chinese characters in event title. But it's fine with English title.

2) Cannot create new calendar event with on Mac OS X. Cannot update existing event with Chinese characters.

Server error message is: "EXCEPTION: <NSException: 0x5614b7615688> NAME:NSInvalidArgumentException REASON:Tried to add nil to array INFO:(null)".

Issues was fixed by reinstalling sope + sogo.

I upgraded from sogo-2.3.8 to 3.0, not sure why upgrading sogo didn't cover this.
