I see similar warning messages when changing to a custom sub theme. I use open social distribution and just recently updated to version 8-x-1.8 and consequently drupal 8.4.3. While the regular open social's "social blue" theme is active, I see no errors, but when I change to the subtheme I created, I get the following errors:

@all

I am not able to reproduce this issue.

1. Installed the module and navigated to "/admin/config/people/terms-of-use" with Logging and errors on.
2. Module version 8.x-2.x
3. Drupal core version 8.6.0-beta1

Can you please list down the steps to reproduce ?

Hi, also get this.

Drupal: 8.9.5

- composer require 'drupal/terms_of_use:^2.0'
- drush en -y terms_of_use

When I went settings page I got varning message /admin/config/people/terms-of-use

That was all what I did
