Ok, thanks for the reply. I went in and double-checked zSEO, and I never had url rewrites on, it's always been off.
I went and did #2, then turned zSEO back on, still the same thing. 404 error because the links to threads in the archive are being changed. When I turn zSEO off, they are back to normal again and working. Must be a setting in zSEO that is causing it, but I definitely have url re-writes OFF.
