I've had a the calendar widget in the footer of my website for several years. The link for the prior month is behaving oddly. Instead of just showing the calendar for November, it goes to a "Not Found" error page. The dates show the proper dates of postings, but when you click on an individual date it does not go to the correct post.
What I've checked or tried so far:
- There is one post in November.
- I deleted the widget and installed fresh.
- Cleared my cache, figured it couldn't hurt
What is really bizarre is that the theme changes to twentyten. My theme is a child theme of twentyten. How is this possible?
