Cups - "client-error-not-found" error
 

I have a RH8 box running cups / samba combo to share printers to the rest of the network .... Through the web-based :631 config, last week I was able to go into the "configure printer" option to change parameters with no problem. Now when I try to click on it I get a "client-error-not-found" message on the screen, and nothing in the error log at all. The only thing changed this week is I added another printer via the web config .... and neither of the two can be configured.

If I delete the new printer, I still get the error when trying to modify the one that worked before.

Any help with this would be great, thanks.
