Webspace without domain

[tought]

Hi There

My question is: is there a possibility to use a webspace without a domain?

in confixx you can find your webspace with: webx.domain.tld (webx is the username)

Is there something similar in ispCP?


My other question is:

I have an error:

PHP Code:

Warning: is_file() [function.is-file]: open_basedir restriction in effect. File(/usr/bin/python) is not within the allowed path(s): (/var/www/virtual/domain.tld/:/usr/share/php/) in /var/www/virtual/domain.tld/htdocs/settingsfunctions.php on line 188

and

PHP Code:

what is the problem and how can i manage this to work?
