I'm getting the following error on my Drupal 8 configuration page;

Entity/field definitions Mismatched entity and/or field definitions The following changes were detected in the entity type and field definitions. Content

Update the node.rng_capacity field.
Update the node.rng_registrants_duplicate field.
Update the node.rng_registration_groups field.
Update the node.rng_registration_type field.
Update the node.rng_reply_to field.
Update the node.rng_status field.

I'm not sure what caused these issues or how to go about resolving them - I think they may be leftover fragments/elements from when I deleted a registration or entity type maybe?

    The message shouldnt mean there isnt anything bad going on. Running drush entity-updates on your site should cancel these messages. – Daniel Apr 21 '16 at 17:42

You can solve this issue by two ways If you have Drush -

drush entity-updates

If you don't use Drush add following script before $response->send(); in index.php file(located in Drupal root folder) and reload the web page.

try {
catch (EntityStorageException $e) {

Then remove this code from index.php file.

  • Can you post drush comment warning or error here? So I can figure out what is the problem exactly. – Rahul Dec 5 '16 at 4:01
  • I deleted my comment, the problem was with the PHP version my drush was using ( I had two versions, shell was using the old one, so drush was too). Thanks! – Chayemor Dec 6 '16 at 10:18
  • If anyone comes seeking this question how to change PHP version under which drush is running you can find this article helpful. <a href="fuelforbrain.com/… to change PHP version that drush runs under?</a> – Rahul Dec 7 '16 at 7:25
  • I had this problem after updating from Drupal 8.3.2 to 8.3.3, but in my fields contained already data. <blockquote>The SQL storage cannot change the schema for an existing field</blockquote> Is there no simple way to update field storage and solve this mismatched entity error when there is already data in the fields? – drupalfan Jun 17 '17 at 11:18
  • Drush didn't work in my case for some reason, but I was able to use drupal update:entities instead. – Gruffy Jul 26 '18 at 8:33

For Drupal 9 use this Module to do the entity update (with or without drush):

Entity Update
