i had the same problem after changing domains. i did everything of the above and it didn’t work. by chance i happened to go to settings and permalink and change it from custom structure (which I had set originally) back to default and back to custom again — saving each time. everything now works.
Any idea of spell checkers that work for WP2.03? None of the ones on Codex work. Even apwllbound is not compatible with my firefox 1.5
