Error message when trieing to edit some setting like user

[marcoH]

I get following error code ewhen i try to update usersettings...

"Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/usr/share/pear/Dataface/FormTool/text.php) is not within the allowed path(s): (/home/sites/site17100:/home/sites/www.ncs.nl:/usr/lib/php/:/usr/share/php:/tmp:/home/sites/general) in /home/sites/site17100/web/veiling/dataface/Dataface/FormTool.php on line 654"

Anyone got an idea what could be wrong...

To assist anyone i have crated a test account:
User = test
Passw = test001

What do you mean update user settings? Like update the information on a particular user? Can we get the test site address to use that test account on?
