BUG Add a Tag page not working

Steps to reproduce

  1. go to all tags -> https://www.ratebeer.com/tag/showall/
  2. Click on the ‘Add a tag’ button, which takes you here -> https://www.ratebeer.com/Tags/tagmanage.asp
  3. Pages lacks the functionality for adding a tag. Here is what i see.

It’s been almost a year since this was posted (and got no answers whatsoever), and today as I was trying to add a tag it happened to me as well. Is this a recurring problem, or has it not been solved in the past 10 months?

It works, at least for admins.
If you have a tag to add, post it here with a description and I will add it
