[WP 3.4.1] permalink to pages gives 404 error while posts are working fine

Hi there

I have noticed that after upgrading WP to version 3.4.1 all the pages permalinks are giving 404s. the posts and categories are working fine.

i disabled all the plugins, resaved the permalink, making sure the .htaccess is writable (chmod 666), and nothing worked. anyone can please help?

my current .htaccess is as follows:`
#########################################################
RedirectMatch (.*)\.htm$ http://www.mysite.com$1

<Limit GET POST PUT>
order allow,deny
allow from all
</Limit>

AddHandler cgi-script .cgi .pl .pm

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
