You don't have permission to access JOOMLA?

Question

Joomla

SOLUTION:
At the very end of htaccess
I registered the rules for the files I need

RewriteCond %{REQUEST_FILENAME} !(/m/mail\.php)$
RewriteCond %{REQUEST_FILENAME} !(/m/map\.php)$

There is such a domain vkomforte.kz
The site is made on Joomle. I didn't make it.
In the root of the site I created a folder / m
I uploaded the mobile version there.
Problem: When sending applications with /m, an error occurs You don't have permission to access /m/mail.php
What line should I write in htaccess which lies at the root of the site that is made on joomle?
Here is the htaccess code:
