[aur-general] Apache (Roundcube) and /tmp

Hi, I tried to install roundcube (in community/), but it fails when it tries to check if he can write in his temp dir, which is a symlink that points to /tmp/roundcube and is rwx for http (and group http too). I have the same problem if I try to put the symlink to /var/tmp/roundcube, but it works with /var/lib/roundcube Note that I update the open_basedir each time, and absolutely no message show in the logs concerning fails to write in /var/tmp or /tmp (only when I forget to change the open_basedir value for php). Any idea where it can come from? Did I miss something in apache (or php?) configuration? Thanks in advance! -- Ismael
