Hi, You can easily create a new instance. There's an example script for it here: https://github.com/Intermesh/groupoffice/tree/master/www/go/modules/community/apikeys/examples But the Multi instance module is not able to install / uninstall modules. You'd have to talk with the instance API which is ...

Do you expect all members of the organisation to be auto filled? It doesn't work that way. It only shows the organisation if it has an email address.

Yes, we'll reimplement it later. You can achieve the same with a custom filter in the address book by the way.

Thanks, we removed the restrictions for you via support.

Are there any errors in the log file or browser console?

Try to enable debugging. And then reproduce the error. Please post the relevant part of the debug log.

I found the problem. Will be fixed in 6.4.84.

That's odd. How do you open the page with the access token obtained via the API call?

I've seen this before. This happens when your server is not using the pdo mysqlnd driver. Can you check that?

I'm afrtaid it's quite rare indeed. But I have successfully tested it with WAMP.

Sorry, there are no options for it at the moment. We plan to improve this in the new framework later.

You can use the command line for it:

php groupofficecli.php calendar/event/deleteOld --data=2016-01-01

Aha, sorry I tried with the Composer where this is impossible. The next 6.4 release will fix this.

Yes sorry
