Try going to Options -> Permalinks and click “update Permalink Structure” at the bottom just to “rebuild” things.
Does that help?
Do you still have your .htaccess in your WordPress directory?
This is a bit unorthodox… but yes, I’d delete it. Then revisit options -> permalinks and have WP build a new copy
(this assumes the current contents are ONLY the WordPress stuff, of course).
Ugh, that didn’t work either
Did it rebuild the .htaccess at least?
Do you have a backup copy (pre update) of it that you could compare with what’s there now?
Unfortunately, no, I don’t.
I’m about THIS close to exporting the posts as XML, deleting the install, and doing it as a fresh one.
