Custom Types 404 after update

This is strange.

Can you check this:

1. Make Sure Types is updated, and only Types is active
(check the issue)
2. Update the Permalinks (once to something else, and then back to what you wish)
(check the issue)
3. Select ALL Custom posts in Dashboard > your_custom_post > All > Select All > Bulk Actions > Edit > Apply > Update with NO changes at all

If this does not work, we need a Site’s Copy, and that is not possible here, so then you would need to head over to the dedicated Support Forum (it’s accessible after a free subscription)

Please let us know 🙂
