Well, I goofed up.
I created a custom site column in the Content Type Hub with the wrong name. I accidently pasted the description of another custom site column to the name field for the next custom site column. The description in the name field is 276 characters with spaces.
When I try to delete the bad custom site column, I get “Sorry, something went wrong. An unexpected error has occurred.” If I try to change the name of the column to what it should be I get the same error message.
Anyone have any bright ideas on how to fix my screw-up?
