Apache Configuration Question

Using mod_write for cleanurls with Lets Encrypt

I have enabled Let's Encrypt on a server running Apache on Ubuntu 14.04 and used the auto option to re-direct all http requests to https. This is working fine.

However, I now want to use mod_rewrite to use cleanurls on my site - all I need to do is remove the .php extension from all filenames. (e.g. routes to

I have tried adding the following rewrite rule to the .htaccess file:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

This configuration works fine on my localhost setup (without SSL) but does not work on the instance running Lets Encrypt.

I have tested that the .htaccess is working by adding this rule which works as expected (redirecting all www requests to the root domain)

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

I suspect that there may be some conflict between the Lets Encrypt auto setup option and my mod_rewrite rule but I am stuck as to how to make them both work together.

Any help would be much appreciated.

Disable MultiViews in .htaccess:

Options -MultiViews

MultiViews (part of mod_negotiation) is likely resulting in a conflict. This does something very similar to what you are trying to achieve using mod_rewrite. With MultiViews enabled (possibly enabled in the server config, although the default is disabled), a request for /filename, will result in Apache looking for a file that matches (that would return the appropriate mime-type) by stepping through the files in that directory (essentially trying various extensions where the basename matches).

I have checked what REQUEST_FILENAME is returning - it is the path to the filename (e.g. [REQUEST_FILENAME] => /var/www/sitename/public_html/output.php)

Yeah, that's the problem. MultiViews has already "fixed" the URL (output to output.php) before mod_rewrite has been able to do its thing.
