I'm using the wordpress archive widget in my sidebar. The permalinks are set to the format: website.com/year/month/
All of them work except January. I have not set any custom links or changed any settings.
My website is https://kristinbytheocean.com/
Please navigate to the archives section and click January to see the error. If on a phone, it's at the bottom of the page. If on a computer it's in the right sidebar.
Why is this happening and how can I fix it?
