Need help with archive issue

[powerwriter]

I am still using version 1.3. Will upgrade after I get this problem fixed. My site has worked fine for years. Now, I'm having trouble. The archives won't work. I get a 500 error plus a 404. A screen cap of my current configuration is at www.susannahutcheson.com/gmscreencap.jpg.

This site is a sub-directory of my main site, powerwriting.com. All else is working. I do have an .htaccess file in it.

I have no idea why all of a sudden it quit working. I do know my server did an upgrade about six months ago.

Any help would be appreciated.

Thank you.

Susanna

The screen cap is gone. A server upgrade could affect how certain files are processed and could cause trouble.
