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..

One, a live link would be really helpful here. Two, it is unclear if this is one issue or two separate issues: permalinks/rewrites, and navigation menu. For the latter, we need to see your custom-Theme navigation menu code. – Chip Bennett Apr 23 '12 at 16:00

Never try to upgrade that many versions in a single step! You will need to carry out a series of smaller, manual, upgrades: 2.7 -> 2.8 -> 2.9 -> 3.0 -> 3.2 -> 3.3.1 ->3.3

I would deactivate all plugins and switch to default theme when you get to current version, switch themes to what you are using and see if it breaks - if so, it will need to be updated - start activating plugins one by one to make sure they work - I'm sure all of them will prompt for an upgrade - you should do that 1st

During upgrade do they upgraded any menu code.. – Dilip Rajkumar Apr 23 '12 at 15:36
during auto upgrade, all the core files including wo-content folder get updated – Tara Apr 24 '12 at 16:15
Hay thanks for all your help finally I found out one bug. The problem is because in wp_options table I had ./ for home (row id 37)variable. Because of that only all the issues. I dont know how it got corrupted. – Dilip Rajkumar Apr 25 '12 at 9:37
