I think I just fixed this issue. Please retest this with v6.4.159 when released later today.

Yes it's intended. Because it can cause problems with meeting requests.

Please check your PHP error log for errors. There should be errors logged when this happens.

You can also try to enable debug mode and then replicate the problem. It should not redirect but output the error.

Sorry, you need to be allowed to create a trigger on your database to do this upgrade.

What's the HTTP status code from the sse.php request?

You filled that in during install!

The procedure looks ok. But the core_user table should already be there when you get to this query.

Can you retry and check if there are errors prior to that? I think something else went wrong before.

Can you send a screenshot? I'm not familiar with that. Perhaps it opens the install page?

We will look into threading!

If the contact doesn't have a name it shows blank. You can enable the email address column in the grid to distinct them.

Can you replicate the error? I tried but can't replicate it.

The URL at System Settings -> General is probably misconfigured.

The query shown here: https://groupoffice.readthedocs.io/en/latest/upgrade/debian.html#from-older-versions-than-6-3 to update pa_mailboxes should fix the password problem!

Please ignore that documentation. It's from an older discontinued project.

These are the actual docs:

I can't replicate that. If the organisation has an email address I can autofill it.
