WordPress 3.3.1 and Permalinks

I have something a bit similar – new site with fresh WP3.3.1 -links from my amazon astore go to a 404 error page.
I also find the edit for hyperlink, add category, and add tags do not work on the main edit page.
Have had an enquiry out for 3 days, so far no response that I have seen

I have found out that /%postname%/ works but:

All my categorie pages give error 404 at that moment…..

So some how there muste be something with this update which causes this…

Did you try deactivating all your plugins (if you have any installed) ?

None are activated…..

I have made some changes to the .htaccess file:

# 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]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Originally there was only the first section – adding the upload part sorted out the lack of editing – now if I can only solve the astore link issue…

ISP helped.
1. Checked with ISP – the site is hosted on epanel and needed the ISP to put a /tmp folder in place.
2. ISP removed the index.php welcome page set up with initial site.
Bingo.
