Hello, I'm trying to symbolic link "/usr/share/squirrelmail" to "/var/www/webmail_lnk", but suPHP prevents it from work. Although the config file "/etc/apache2/mods-available/suphp.conf" tells suPHP to be disabled on "/usr/share", Code: <Directory /usr/share> suPHP_Engine off </Directory> The script not working, and I got error 500 and these lines in the log files. /var/log/suphp/suphp.log Code: [warn] File "/usr/share/squirrelmail//index.php" is not in document root of Vhost "/var/www" /var/log/apache2/error.log Code: [error] SoftException in Application.cpp:221: File "/usr/share/squirrelmail//index.php" is not in document root of Vhost "/var/www" I know it's not required in this case, but I tried to add the directory "/usr/share/squirrelmail" to suPHP docroot but nothing changed. Code: docroot=/var/www:${HOME}/public_html:/usr/share/squirrelmail There is another server with the same configuration works properly as expected. I've compared the suPHP config files "/etc/apache2/mods-enabled/suphp.conf" and "/etc/suphp/suphp.conf" on both servers, the files are identical. It works only if I disabled the "check_vhost_docroot" which isn't an option. Why would suPHP behave like this, is there anything missed ? Note: The server is perfect ISPConfig installation, ubuntu 12.04. Thank you,
