I'm working on reviving (and upgrading the EE 3)n a site that has been moribund (no posting) for about 18 months. The home page index displays OK, but if I click on any story or try to view the next page of the index, I get a blank page with the message "File not found."
I don't know when the site stopped working. It's running EE version 2.10.1. The back end and control panel seem to work fine.
The site is at http://coastsider.com
Any idea what might be going on here?
