Warning: Failed to write session data ?

Hi, I get this message when I load my webshopsite into a frame on onother server but not until I press a form button: Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/apachefs/sessions) in Unknown on line 0 I can´t change settings on my webhost. If I load another page first wich start the session and sets a sessionvar, it works fine. Is there a way to workaround this problem. I use input type =hidden name=PHPSESSID value=echo $PHPSESSID.to pass the session in my form. I also noticed that You can´t view source of this frame loaded from another server. I have my mainsite on one server and shopsite on another. Thanks in advance for any help. -- Regards, Jan Grafström Sweden
