This was so simple to fix, but I can't believe how long it took me to find the answer.
My archive links wouldn't work on my WordPress installation.
- The archive page was fine and visibile -- but when I clicked on a month, it would take me back to my home page.
- The archive widget was also there -- but, again, if I clicked on a month, I got taken back to my home page.
- And my date filters wouldn't work on the post admin panel, either. Every time I tried to filter my postings by date, I was brought back to the main post admin screen.
Here was my fix.
I had installed the Robots Meta plugin. The plugin is great and works well, but I had disabled the date-based archives (and author-based archives) in the configuration panel. Unchecking those boxes gave me back full access to my archives and using the filters on the post admin panel.
A simple decision that had major repercussions. But a simple fix.
Now I hope that I've saved you all the trouble I went through.
