Error in Custom Communication

Not all the time I see this error, but about 1/3 of the time.

In customers order, and then ad-on communication, I get this error…

Warning: chdir() [function.chdir]: open_basedir restriction in effect. File(/usr/local/lsws/fcgi-bin) is not within the allowed path(s): (/home/milezone:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp) in /home/milezone/public_html/core/fn.fs.php on line 121

Now when I enable the add-on (so I can communicate with customer in their order) the error code goes away.

I showed this code to my main man and pro modder “Joe” and he says this is a problem within cs-cart, or possibly host.

Any ideas?
