Adding spaces to tags

[ChrisMontius]

  Suddenly, I am no longer able to use tags with spaces or any 'special characters'

 I have hundreds of existing tags for specific locations and species/genus of plants.

 I can access what I have, but I can no longer edit with the tags.

 I use the tags for work purposes not for social media.

 ANY THOUGHTS? I need HELP.
