Categories problem — index.php everywhere

Hi!

I am using 3.1.2 with (“customized”) bytesforall theme. The problem is that now (sorry, i can not tell when and after which change) my wordpress ignores any category-*.php template and uses index.php only.

My .htaccess is “typical”:
#——————-8<————————–
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
#——————-8<————————–

Please help!
