This problem came out of the blue. I've made no configuration changes other than adding software and setting up mysql - printing works OK.
This problem is isolated to a laptop, other computers on the network are fine.
After typing localhost:631/. into Konqueror and getting the 404 Not Found error, I tried starting the cups interface from the System menu. This produced a 'white' featureless web page displaying only the link text - none of the usual cups interface, buttons etc (konqueror and seamonkey).
It was possible to connect to all the links except Home.
On a second attempt at starting the cups interface from the System menu, Konqueror displayed the 404 not found error only - no web page! However, I'm still able to access Administration etc by typing the full address e.g. http://localhost:631/admin
, but not localhost:631/. (which is the equivalent of Home).
Is their a correlation between the inability of the cups interface to render a complete web page and problems connecting - not sure about that?
I've reinstalled cups several times with no success. At this stage it seems that removing cups and all of its configuration folders then reinstalling is the only option remaining?
