Hello again! Allthough i have searched the entyre forum for this problem i havent found anything, if you have the response for my problem, please just link to it ! i have ISPConfig 18.104.22.168 installed, everything is ok, just one issue with one of the settings inside the vhosts: i have installed Roundcubemail the version is not important because a had the same problem with 3 different versions. i have created a website mail.mydomain.com and manually adjusted the path to go to /usr/share/roundcubemail. i had to comment this line inside the vhost settings in order to make roundcube interface to work: #php_admin_value open_basedir /home/www/clients/client4/web24/web:/home/www/clients/client4/web24/tmp:/home/www/mail.mydomain.com/web:/srv/www/mail.mydomain/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin:/etc/phpmyadmin:/var/lib/phpmyadmin i have followed some of the steps from here - http://www.howtoforge.com/forums/showthread.php?t=51764 - in order to create an alias /mail for roundcube ( i want to use also /webmail (squirrelmail) in the same time ) for a website that has the above line commented out, the alias /mail is working; if not, i get : You don't have permission to access /mail/ on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. as an example: http://www.mydomain.com/mail - gets the above error, because of the mod-php line not commented out. is there a way i can stop for good that line for being active insinde newly created websites, and if it`s stopped, ( i might know how to disable it from ISPConfig interface - System -> server config -> web -> PHP openbase_dir line ) could some php scripts, CMS, etc.. not work anymore ? Thank you !
