WSOD when trying to configure menu with many items I have a menu with many nested/multi-lingual menu items (I don’t know the exact number, probably something around 2000-3000).

Whenever I try to visit its configuration page in the backend (/admin/structure/menu/manage/menu-foobar), I get a WSOD after some loading time.

The site is hosted on a shared webhost (PHP memory limit is at 256M; max execution time at 120), so I assume it might work to move to a more powerful VPS, but I wonder: 

Is there any way to access the menu configuration page without moving to a better server or changing the site architecture (i.e., using several menus instead of one)?

I tried the Menu Admin Splitter module, but it didn’t help.
A fiddly workaround:

On the "list links" menu page, you can visit, rearrange, enable/disable, edit, and delete all menu items. Except for visiting the node, all this is possible from a single menu item’s edit page. 

But how to access the menu item edit page without being able to access the parent’s menu page listing all those items?


Visit the node whose corresponding menu item you want to edit.
Open its HTML source code.
Search (Ctrl+f) for active menu-mlid. You’ll find a class value like menu-mlid-218. 218 is the menu item ID.
Visit /admin/structure/menu/item/218/edit.
