Grid Media Library Won't Load in 4.0 w All Plugins Disabled

Reported by: johnstonphilip's profile johnstonphilip Owned by: sergeybiryukov's profile SergeyBiryukov
Milestone: 4.0.1 Priority: normal
Severity: normal Version: 4.0
Component: Media Keywords: has-patch commit fixed-major
Focuses: ui, javascript Cc:


Upon upgrading to 4.0, on 10 of my WP installs, everything is working perfectly.

However, in 1 of my installs, I can't get anything to show when the Media Library ("Dashboard" > "Media") is set to "Grid" mode. Rather, the spinner wheel just spins forever.

It DOES load correctly when I have it set to "List" mode.

I have WP_DEBUG mode on and no errors are showing. There are also no javascript errors showing in the console on Google Chrome.

Steps I have taken already:

  • I have de-activated all plugins and reverted to the twenty fourteen theme
  • I checked the server to make sure there is enough RAM, Hardrive space, and other resources.
  • I checked permissions in apache and all are set to be owned by apache
  • I restarted Apache
  • I restarted the entire server (which is a LAMP setup)
  • I have reverted to 3.9.2 and back to 4.0 multiple times (there is no "grid" mode in 3.9.2)

  • Keywords has-patch commit added; reporter-feedback removed
  • Milestone changed from Awaiting Review to 4.0.1

You have some images attached to non-existing posts.

Normally, wp_delete_post() makes sure not to leave orphaned images.

Still, we should check if the parent post exists, like we do in class-wp-media-list-table.php.

See 29566.patch.

Good call Sergey - thanks!

P.S. do you know if there is a way I can filter media to show items like that: that are attached to a post which has been deleted?

Additional possibly related. Contributor role granted upload_files, grid view ajax in add media not showing uploaded images.

Media library - view all - grid view / not showing uploaded images, list view showing images.

I got the same error and discovered that in my functions.php used the wrong hook to run remove_menu_page.
(admin_init instead of admin_menu)
