I host on my own VPS. Checked my error logs, but there was nothing there. Tried again when I got back from work, and was about to re-upload the wp-admin/nav-menus page, when I saw WP4 was out. Just updated, and my menus are back.
Odd, but oh well. I’ll take it 🙂
Thanks for the assist, everyone.
Hi James,
Thanks for your reply. I just tried what you suggested, but neither deactivating all plugins nor switching to the default theme made a difference. The menu page continues throwing an error.
Any other ideas?
Thanks!
Peter
