Prevent PHP execution failed - permission denied

Hi,

While trying to add the htaccess file to prevent PHP execution of this file I received this error:

file_put_contents(/home/content/p3pnexwpnas04_data03/38/2440238/html/wp-includes/.htaccess): failed to open stream: Permission denied in /home/content/p3pnexwpnas04_data03/38/2440238/html/wp-content/plugins/wp-defender/app/module/hardener-module/component/class-wd-protect-core-dir.php on line 380
How do I fix this?
Thanks
