Webmail issue

[skoena]

I get this when I open mydomain.com/webmail
(other domains do not have this issue?)

Warning: Unknown: open_basedir restriction in effect. File(/usr/share/squirrelmail/index.php) is not within the allowed path(s): (/var/www/clients/client1/web3/web:/var/www/clients/client1/web3/tmp:/var/www/mydomain.com/web:/srv/www/mydomain.com/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin) in Unknown on line 0

Add /usr/share/squirrelmail to the open_basedir field on the Options tab of your website in ISPConfig.

Added it but I still get error:

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(config/config.php) is not within the allowed path(s): (/usr/share/squirrelmail:/var/www/clients/client1/web3/web:/var/www/clients/client1/web3/tmp:/var/www/mydomain.com/web:/srv/www/mydomain.com/web:/usr/share/php5:/tmp:/usr/share/phpmyadmin) in /usr/share/squirrelmail/index.php on line 15

ERROR: Config file "config/config.php" not found. You need to configure SquirrelMail before you can use it.

Strange that it came up out of nothing and no other domains have this issue?

Did you compare your open_basedir setting with your other (working) sites?

It's exactly the same.

Strange because I didn't change anything for this domain, from one to the other day it stopped working.....
