Fixed two roundcube bugs

Hello,
I needed to install the new Roundcube version on NGINX / Debian to use some of the new messaging features.
The update of Debian 9 in Debian 10 has caused some Roundcube dysfunctions. Here's how to fix them.
1. Messaging is unreachable.

This comes from the update of PHP 7.0 in 7.3.
The RoundCube webmail is accessible on a Nginx ISPConfig web server through the vhost application. The PHP-FPM vhost applications runs under the user and ispapps group. To correct the Roundcube error, you must change the owner of some RoundCube files.

Code:

chown root:ispapps /etc/roundcube/debian-db.php
chmod 640 /etc/roundcube/debian-db.php
chown root:ispapps /etc/roundcube/config.inc.php
chmod 640 /etc/roundcube/config.inc.php
chown -R ispapps:adm /var/log/roundcube
chmod -R 750 /var/log/roundcube
chown -R ispapps:ispapps /var/lib/roundcube/temp
chmod -R 750 /var/lib/roundcube/temp

2. Completing recipient names does not work properly when groups of contacts are created.

The problem is a bug in regex management if updating the installed Roundcube version that was installed is a bit dated.
Find /lib/Roundcube/rcube_vcard.php
Replace

Code:

'/\n+/',                 // remove empty lines
'/^(N:[^;\R]*)$/m',      // if N doesn't have any semicolons, add some

By

Code:

'/\n+/',                  // remove empty lines
'/^(N:[^;\r\n]*)$/m',     // if N doesn't have any semicolons, add some

 

Warning: it was the installation of multiple versions of PHP that brought a problem of rights. The problem has apparently disappeared.
However, adjusting the permissions now produces an error in tutorial of Perfect Server Debian 10 NGINX.
