I allowed Defender to harden my site by preventing php scripts and now my ajax file won't work.

After hardening I have this htaccess file in wp-content

## WP Defender - Prevent PHP Execution ##
<Files *.php>
Order allow,deny
Deny from all

I like that but there doesn't seem to be a way to allow certain files to run. So, my ajax file in a plugin won't work.

I'm guessing I may need to implement it another way but Is there a way to allow that file to run in the mean time?

Will this prevent other plugins from running an ajax script?
