So I had panels installed and was playing around with the node_view default page. I uninstalled panels, reinstalled it, then later upgraded to the latest version. But the fact I was editing that page seems to have been remembered and it says "locked." When I click on it I get WSOD. This is the only page getting WSOD.

I finally unlocked it. I searched through my history trying to find any pages I could access and hit
admin/build/pages/nojs/operation/node_view/actions/configure/choose
I clicked cancel and it appears to be working

When you get a WSOD this will usually be accompanied by an error in the apache, php or watchdog logs. That error is key to solving these.

I was getting the WSOD on database update after upgrading panels.
After reading the above and checking logs, resolved this by removing the old panels directory before downloading the new version.

The log error: PHP Fatal error: Cannot redeclare panels_stylizer_lipsum() (previously declared in /disk1/data/drupal-test/sites/all/modules/panels/panels.module:410) in /disk1/data/drupal-test/sites/all/modules/panels/panels_stylizer/panels_stylizer.module on line 247

That error means you upgraded the module incorrectly. When upgrading modules, you need to remove the original directory to get rid of old files. In this case, a module was removed but the old files are still sitting around and causing problems.
