Hi @zogstrip,

Following this: [Db:migrate fails on discourse-calendar - #2 by sam](https://meta.discourse.org/t/db-migrate-fails-on-discourse-calendar/124229/2)

It also fails for stable branches (concretely the latest one `v2.3.3`)

```bash
rake aborted!
NoMethodError: undefined method `register_user_custom_field_type' for #<Plugin::Instance:0x00005584c81a8158>
Did you mean? register_post_custom_field_type
               register_group_custom_field_type
               register_category_custom_field_type
               register_topic_custom_field_type
/var/www/discourse/plugins/discourse-calendar/plugin.rb:72:in `block in activate!'

```

Any plans to fix it?

Just [backported](https://github.com/discourse/discourse/commit/39a427efce3202bf771ff61b2c28289afd250ec7) to stable. Can you update and try again?
