when I click on “Contacts” in Roundcube, it redirects to this page:
but the Browser (Chrome) displays the following:
This page isn’t working
mail.domain.de is currently unable to handle this request.
HTTP ERROR 500
Mine navigates to the same page, but just loads the Roundcube contacts page.
Have you modified anything in MiaB?
I just found the error and I want to share it here:
I had two Domains: mydomain.de and mydomain.name. The name-domain was my testdomain for the original setup of MIAB. After all worked, I moved the production domain (de-domain) also to MIAB.
The mail-subdomain was first mail.mydomain.name and later mail.mydomain.de. But in the SQLite DB was still the path for the name-domain. The DB is in /home/user-data/mail/roundcube and I copied it to my computer, opened it with DB Browser for SQLite and look in the table carddav_addressbooks. In the column url was the path https://mail.mydomain.name:firstname.lastname@example.org/contacts/
I just changed the TLD from name to de and copied the file back to the server and and worked, but don’t forget to set the file rights:
chown -R www-data:www-data roundcube.sqlite
