Gmail Calendar Invites Throwing Errors in Roundcube

[gabrio]

hello guys,

Since a while i am having problems accepting Google Calendar events in Roundcube, my sysadmin said this is a known issue/bug and i wanted to ask if anybody found any workaround.

Basically, i get an internal server error when there is a google calendar invite i need to accept.

Currently i don't have the ACCEPT - PROPOSE NEW TIME BUTTONS as well

However, if i import the invite.ics attachment that comes with the calendar invitation, it works and i get the ACCEPT - PROPOSE NEW TIME, etc

or if i save an event manually, it works, but took some deleting calendars back and forth.

This is how it looks from the calendar invite https://www.dropbox.com/s/steckkbkchl1ymh/Error2.png?dl=0

This is the error that often comes up https://www.dropbox.com/s/rtksc96un99rfuh/Error1.png?dl=0

This is if you import the calendar.ics file instead https://www.dropbox.com/s/v7nak8vdv74puzw/Error3.png?dl=0

Then if i accept that and then delete the meeting (he says sending a response), then it will throw again the internal server error.

BUT if i accept with the invite.ics download, then the invite looks like this now where previously there was the wheel spinning only. https://www.dropbox.com/s/7g6mfzdfuhnow0b/Error4.png?dl=0

that's where i got it at.

thanks,
Gabrio
