RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$

RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^.#?\ ]+\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^([^.]+)\.php$ /$1 [R=301,L]

Answer 1

Assuming that your AJAX requests go to the /includes folder, and your normal pages do not, we can modify your rules a bit so that they look like this (including Cags' comment about the RewriteCond):

Options +FollowSymlinks
Options +Indexes

RewriteEngine on

# We'll do the redirect first, so no other rules get in the way
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /([^.#?\ ]+)\.php([#?][^\ ]*)?\ HTTP/
# Make sure the request didn't start with "includes"
RewriteCond %1 !^includes/
RewriteRule ^([^.]+)\.php$ /$1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ $1.php
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]

I also think that you either wanted /? at the end of the rules in the center block, or /$1/ as the replacement on the rule in the first block, so that the redirect from /page.php to /page gets interpreted correctly after the first redirect (I think right now you'll get redirected twice, once by the first block, and again by the last block).
