In my experience, the statistics panels ('Most Edited Pages', 'Current
Month Activity', 'Most Referred Pages') hogged the panel editor (they
are disabled in my wiki). Stil, I prefer not to use the somewhat
unreliable Panel Editor and declare what panels to use under
Presentation > Left Panels instead.

Hi Chris,
sorry for the late reply. Here's what you can try doing in order to debug
this issue:
- Go to .../xwiki/bin/view/Panels/
- Try opening the various panels listed on the page and see if one of
them hangs (ie, its page does not display)
- If you find one, replace "view" by "inline" in its URL and
comment it
out by adding #* at the very beginning and *# at the end, then save it
- Try accessing it again
Once you've identified and "fixed" all such panels the panel wizard should
work again. You could also log a JIRA issue noting that this should be
fixed in the default distribution.
Thanks,
Guillaume

Hi Guillaume,
I commented out both panels, and no luck.
Any other suggestions?

Hi Chris,
to fix this, you can go to .../xwiki/bin/inline/Panels/Navigation and
comment the panel out (same for the other one). You'll lose that panel,
but
you'll win your ssytem back.

The panel wizard renders all the panels and so if you have a panel
that uses a lot of resources (CPU/Memory) it will slow down or even
block the panel wizard. From my experience, the panels from the
standard XAR that cause problems on large wikis are Panels.Navigation
and Panels.SpaceDocs because they don't limit the number of pages
displayed and both are loaded synchronously (when the page loads, so
no AJAX). The description of Panels.Navigation warns you about this:
"However when your wiki grows you'll usually want to replace it with
your own fixed navigation".
Hope this helps,
Marius
