I recently noticed that only 1 post was showing in the fronpage. I had made no changes, other than upgrading a theme and converting the blog to utf-8 from latin-8859, and several other minutiae. :)
So, I changed to another theme, and another, and, yet another. All themes exhibit the same behavior. Only 1 post shows when you visit the site. After I log in, it shows all the posts. I changed how many post to show to 11, just to make sure this was not the problem.
I have not touched a line of code in WordPress, or in its themes, lately. I am surprised by this recent behavior, and worried.
There is nothing that I can find in the forums to lead me in the right direction. Please share any ideas about what may be happening.
