I don't know if the category is correct but we have a client which currently is somehow able to produce the following error:
He can't save a page because Drupal is telling him that untranslatable fields can't be changed while editing not the current revisions.
I had a look at the revisions and saw what is also on the screenshot. Drupal thinks there are 2 concurrent current revisions.
Clearing the cache solved this problem.
The project is using Redis for all caches. Could this be the problem?
Workflows and content moderation is not used.
We have ~ 20 projects using Redis for caching and none has this problem.
I don't know where to start and look here.
Is there someone which has experienced the same?
