[cups-devel] 2.x web interface: blank pages due to redirecting issue

[Michael Sweet]

Peter,

Please file a bug at:

    https://www.cups.org/str.php

We saw this issue sporadically during the development of 2.0 and I thought we had fixed all of the known causes.

After hitting "Set Default Options" the usual page reporting that changes were successfully applied comes up but next there's a blank page. The corresponding URI is localhost:631/admin/?OP=redirect&URL=/printers/<queue>.
