Sorry for my english..!!

I have a problem with RewriteRule

I have the following RewriteRule in. Htaccess

RewriteRule ^productos/impresiones$ index.php?accion=impresiones [L,NC]

at the root of the site there is a productos.php file. and goes to this file instead of the file index.php action = .....

If I delete this file, the rewrite works. If this file exists Rewrite stops working ....

Same with:

RewriteRule ^phpinfo/prueba$ index.php?accion=impresiones [L,NC]

Run the file phpinfo.php

I may be wrong?

I copy the. Htaccess

RewriteEngine On

<IfModule mod_rewrite.c> 
RewriteCond %{HTTPS} !=on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^http://%1%{REQUEST_URI} [R=301,L]

</IfModule>

RewriteRule ^productos/impresiones$ index.php?accion=impresiones [L,NC]
RewriteRule ^phpinfo/prueba$ index.php?accion=impresiones [L,NC]
RewriteRule ^index$ index.php?accion=index [L,NC]
