I clicked on the "Stairway Series" link below an article title and it brought me to the main "Stairways Series" page:
As I scrolled down, I noticed that there were 3 entries for one of my articles: "Stairway to SQLCLR Level 2: Sample Stored Procedure and Function". One of them is listed as "Stairway Step" while the other two are listed as "Revision".
The two listed as "Revision", when the article title is clicked, take you to an error page stating:
Oops! That page can’t be found.
I assume that the "Revision" entries should be hidden.
Take care, Solomon...
