How to reset the display of nodes? For some reason I can no longer manage the display of a node in the backend. Managing the form display works but not the frontend display managing. I get the following error message:


  Fatal error: Maximum execution time of 50 seconds exceeded in
  /customers/2/f/2/igghq.com/httpd.www/core/modules/field_ui/src/Element/FieldUiTable.php
  on line 100


I can still manage the display of other content types. Just not that specific one. Is there a way to reset the manage display backend form, maybee through the database?


running display suite
Drupal 8


More info: it only locks-up when loading the default display mode. Teaser still works
Wanted to post my solution(i encounter it too) if anyone stumble upon.

You don't have to uninstall and reinstall fieldgroup if you know which content type is causing this issue. 


Go to Configuration Export ( [your URL]/admin/config/development/configuration/single/export)
Choose Entity View Display in  Configuration type
Look for your content type in Configuration Name
Copy the configuration that appeared in Here is your configuration:
Open a text file and paste your config.
Look for field_group: , delete it together with it's child or until id
Then re-import your config. 


That works for me without resetting other content type field groups.
