I want to remove field collection module in Drupal 8 as the module has been deprecated. When I try to uninstall after removing the fields from content type the option to uninstall is greyed out.

I get an error

field_collection: There is content for the entity type: Field Collection Item. <a href="/admin/modules/uninstall/entity/field_collection_item">Remove field collection item entities</a>.

  • You need to manually delete all field collections and fields linking to field collections. – No Sssweat Dec 23 '19 at 3:08
  • @Sssweat 1. I removed all fields from the field collection 2. Deleted the field collection from content type (This deletes the field collection) 3. Ran cron 4. Uninstall checkbox is still greyed out – nitnac23 Dec 23 '19 at 3:19

I guess you solved this already, but if somebody else stumbels over this, here my 5 cent on how to get rid of field collection. I encountered the same issue as @nitnac23 and was only able to get it out via direct data base manipulation:

  1. definitely make a DB backup this time (might save your website)
  2. Remove all field collection fields from your entities
  3. run the cron potentially multiple times (this cleanes up the entities - fingers_crossed)
  4. it is important, that you no longer have fields pending deletion as a reason for not beeing able to dissable fields collection (under /admin/modules/uninstall/) - if you still have it, try running the cron again (more infos here)
  5. clear the contents of the database tables field_collection_item and field_collection_item_revision directly in the database
  6. uninstall field collections now via /admin/modules/uninstall/
  7. if you have still field_deleted_* tables in your DB, drop them (I had 12 before runing the cron and still 2 after unsintsalling the module)

That should do it hopefully :)
