Hello everyone,
I tried to use the Panel Wizard to change the Page Layout from the default setting of
"Right Column" to "Left Column". When I clicked "Save the new
layout" I received a prompt "The layout has been saved properly". However,
a stack trace was written to the console. I am now left with no side columns at all.
What am I doing wrong?
Here's the message that is now written to the console when I navigate to the Panel
Wizard page.

New subject: [xwiki-users] Can't adjust Page Layout in Panel Wizard
Hello Folks,
Now that I know that XWiki logs everything to xwiki.log (thanks Vincent!),
I'm including the entire log that is written when I attempt to modify the
Page Layout.
A full description of my problem can be found in the thread below. Any
help is appreciated. Thanks.
