I don’t see all tags in the Tag Meta Box

If a post has tags that you see on the front end but not in the Meta Box on the post edit screen, please follow these steps:

  1. Go to the Tag Groups Settings -> Back End and there to the Meta Box tab and make sure that all groups are selected to display in the Meta Box. Save and return to the post edit screen.
  2. Go to the Tag Groups Settings -> Troubleshooting and there to the First Aid tab and click the buttons, from top to bottom.
