[ic] Attempted database update without permission

[John Allman]

Hi - i recently set up interchange 4.6.5 on a debian stable box (yes, 
there is a reason for wanting the old version) and am now finding the 
admin interface to be acting up. whenever i attempt to add a new product 
it brings me to an error page that says:

"The following error occurred:

Please correct and try again.

/Maybe you need to _*log in*_ 
<http://www.houseofireland.com/cgi-bin/hoi/admin/login.html>?/ "

which isn't very helpful. I then must log in if i wish to view any of 
the admin pages. In the error log i find the following:

192.168.0.145 XTQqvWU7:192.168.0.145 - [17/June/2003:12:31:58 +0100] hoi 
/cgi-bin/hoi/ui.html Attempted database update without permission, 
table=products key=newproduct.

this results from attempting to create a product called newproduct.

can anyone suggest what might be causing this, or a way to work out 
precicely what's going wrong?

thanks

John
