ok i checked the squrirrelmail.conf and noticed it said alias /squirrelmail /usr/share/squirrelmail so i changed alias to webmail and restarted and a new problem arises check the link above once again
Check if you have mod_dir and mod_php5 enabled in apache. ls -l /etc/apache2/mods-enabled/ Do you have php5.conf php5.load and dir.conf dir.load? Did you do this step? Now go to the PHP open_basedir field on the Options tab of your web site in ISPConfig and add the directories /usr/share/squirrelmail and /etc/squirrelmail (that's the directory where SquirrelMail's configuration is stored) to the line, e.g. as follows:
ok php is working http://local.advancetechuk.com/phpinfo.php as for webmail still no luck here is my PHP open_base text Code: [website_path]/web:[website_path]/tmp:/var/www/[website_domain]/web:/srv/www/[website_domain]/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin:/usr/share/squirrelmail:/etc/squirrelmail
