Thank you for the response, @parkdanil!
I double checked that there were no posts with multiple categories. Looks good there.
I went and removed the ‘Running’ category from all posts (by unchecking the Running Category on the post. I did not check the Uncategorized Category).
Behavior is interesting. When I go to https://chrisandlisa1.wordpress.com/running/, it successfully loads a page with no posts. As expected. This is a page in my site that only displays posts in the Running Category. However, when I go to https://chrisandlisa1.wordpress.com/category/running/, I land on the page with Category: Running at the top and a list of all of the posts in the site (those with and without a Category selected. Also noticed that if I go to some other page, like https://chrisandlisa1.wordpress.com/catastrophe/running/ or https://chrisandlisa1.wordpress.com/a/running/, I get redirected to https://chrisandlisa1.wordpress.com/running/. So, it seems to be just the builtin page https://chrisandlisa1.wordpress.com/category/running/ that has the surprising behavior.
I see that you suggested I remove the category from all of the posts in our site and I can try that to see if it makes a difference after checking with the owner of those posts. Although, based on the behavior when I remove the Category from my posts, I’m not sure it will make much difference.
Do you think the Categories and the Tags behavior are linked? That is, do I need to remove all tags in addition to all Categories from posts to test the behavior of https://chrisandlisa1.wordpress.com/category/running/?
Thanks for your help, I really appreciate it!
