I'm not able to reproduce this on NetBox v3.6.5. Best I can guess, maybe you somehow have an ImageAttachment assigned to an object which doesn't have the reverse relationship? But this should exist for all core models, and you don't appear to have any plugins installed.

Steps to reproduce:

  1. Navigate to extras > image-attachments
  2. Select order by parent.
  3. Reload Page

Work around:

  1. Navigate to user > preferences
  2. Reset Table Configuration for "ImageAttachmentTable"

  1. Select order by parent.

Ah, that was not in the original reproduction steps. @bmp521 could you please update the original post above?

The workaround steps from @MrFoxTrot restored access to the page: Customization > Image Attachments as well as the images listed within the locations. Thank you all for your assistance.
