[Dominfo84]

Hi
Sorry for my bad english, i'm french guy
I have Owncloud and I sync my contacts and calendar with my phone Android, well all works fine
I have Roudcube with calendar and calendar plus
In Roundcube, the contacts sync with Owncloud but the calendar wont working

In settings calendar, I put fournisseur caldav / user and password of Owncloud et url https://XX.XX.XX.XX/mycloud/owncloud/remote.php/caldav/calendars/admin/defaultcalendar like to my phone
But in tab of calendar, I see at the left the name of my calendar with ( caldav ) but not event
When I try to put a new event, it disappears with message "Une erreur est survenue pendant l'enregistrement" => An error has occurred during recording

I dont know what can I do for fix that

Can you help me please ?
Thank you

Didier
