I haven’t seen the white screen you describe but after adding a few dozen pages to the custom menu, every gets VERY slow, eg, takes forever to just SAVE. The rest of the WP dashboard pages/functions are zippy.
I don’t have the Global Translator plugin installed.
Hi griffin, from my tests, I confirmed from my tests that the problem I was having was a conflict with Global Translator.
But your problem could be a conflict with another plugin. I’d suggest deactivating all of your plugins and testing the menu editor. It could also be a theme conflict, I’d try switching to the default 2010 theme and testing it as well.
