'Tag is Invalid' - likely due to an unspecified plugin

@Andy02:

  1. The blank tags in the /tags page are caused by Docuss. I’ve just added a section in the doc to explain why. As an administrator, you can use Alt+a to unhide the blank tags and troubleshoot your issue more easily.

  2. I don’t believe Docuss has anything to do with duplicate tags or the “Tag is Invalid” message. Please disable Docuss and see if the “Tag is Invalid” message disappears. If it does, don’t hesitate to file an issue in the Docuss repo.
