Have you received the error “WooCommerce Subscriptions is inactive. This version of Subscriptions requires WooCommerce 3.0 or newer.”
You may also see an error under WooCommerce > Subscriptions saying invalid post type when trying to view all the subscriptions or individual subscriptions. We encountered this error after transferring a clients website from one hosting platform to another.
How to fix this error:
- Backup your database, and make sure both WordPress, WooCommerce, and WooCommerce Subscriptions are fully updated.
- Go to Status under the WooCommerce Menu (WooCommerce > Status)
- Click the Tools Tab
- Scroll down to “Update database”
- You may need to wait a moment and allow the database update to reapply.
Refresh the admin page, and the notice should be gone and WooCommerce Subscriptions will now function.
