   Most likely your theme isn't compatible with the new version. Switch to the default theme and try again.

   Without actually seeing your site or at least knowing what theme your using it's impossible.

   it is probably not a problem with my theme...coz it is saying that table is missing. coz i got similar kind of errors in default theme also when importing old posts

   Because in the upgrade to 2.3 the database schema changed and that table was replace with taxonomy tables. Try the default theme and see if you still getting errors. Also check these out.
