I have upgraded my wordpress from 2.7 to 3.3. Now if I try to change my Permalink /%category%/%postname%/ my home page is loading. However, all my pages are getting 404 page.
I dont know how to fix the problem... I got no log.. Then I changed the theme to default theme twenty eleven then also I faced the same issue.
Then I installed a new WP 3.3 then installed put my theme alone.. now no menu is displayed.. I dont know what is the problem.. any help is greatly appreciated..
Thanks in advance..
