I was editing an entity reference view for one of my content types, it worked well, saved well, and the live form worked well too. Then unexpectedly links in the view editor just became unresponsive. Now, whatever link I click, an ajax http request is successfully sent, but no popup is shown.
Logs reveal the following warning:
Type: theme
Location: .../admin/structure/views/view/animals_entity_reference/preview/default?_wrapper_format=drupal_ajax
Referer: .../admin/structure/views/view/animals_entity_reference
Message: Theme hook not found.
Severity: warning.
The following does not help:
- Clearing cache and logging in/out
- Duplicating the view (the duplicated version has the same issue)
- Disabling / enabling the view
The only workaround I found is removing the view and creating a new one

tim.plunkettFor reference, that error is from
\Drupal\Core\Theme\ThemeManager::render()

dawehnerThat sounds exactly like a duplicate of #2808481: Introduce generic entity template with standard preprocess and theme suggestions
