On CGI you need some rewrite rules:

https://groupoffice.readthedocs.io/en/latest/install.html#authentication-with-cgi-or-fastcgi

It's removed for security reasons. You can find it here:

https://github.com/Intermesh/groupoffice/blob/master/CHANGELOG.md

This one is fixed in 6.3.43!

Should be fixed in the latest release!

Hi,

Change your URL property in system settings to https.

With CGI you need to add the Authorization header:

https://groupoffice.readthedocs.io/en/latest/install.html#authentication-with-cgi-or-fastcgi

Please try again with 6.3.43. This has been fixed.

Normally it launches an installer.

It complains about TLS. Did you setup an SSL certificate?

If not you probably need to disable that.

The second Cron suggestion is the correct one. I’ll correct the other one.

It looks like the error can be fixed by changing the notification settings at system settings. The email address must match the username for your account

Good to hear!

Sorry that’s not possible. It takes the browser language as default or the system settings language if the browser language is not available.

This probably because of a misconfigured url at system settings.

I just checked with a fresh debian 9.5 install and an instal of 6.3.41 works without any issue.

Hopefully this issue is solved then!

The strange thing is that the clean install should create an empty folder /var/lib/groupoffice owned by www-data.
I'm going to test a clean install on debian today. I will make sure next version works.
