Joomla and non-Joomla subfolders

Question

I have a Joomla installation with search-friendly-urls at the root level of the domain, but my host is giving me access to my website stats (which requires authentication) in domain.com/stats, and I cannot see it, just a Joomla generated 404 error.

I thought this might be due to the .htaccess so I tried adding this line to the top:

RewriteRule ^(/stats) - [L]

but I still get the 404. This is what the rest of the .htaccess: looks like

##  Can be commented out if causes errors, see notes above.
Options +FollowSymLinks

#
#  mod_rewrite in use

RewriteEngine On

Answer 1

EDIT: does any of these (directly after RewriteEngine On) help?:

RewriteCond %{REQUEST_URI} ^/stats/.* [NC]
RewriteRule .* - [L]

or

RewriteCond %{ENV:REDIRECT_STATUS} 200 RewriteRule .* - [L]

also, try enabling the

RewriteBase /

if it still doesn't work, and if you are able to change to server / virtual host config, try logging the rewrite process.

EDIT END

try adding a

RewriteCond %{REQUEST_URI} !^/stats

before the

RewriteRule ^(.*)$ index.php [F,L]
