All pages show "You don't have permission to access /index.php on this server".

Hi

All pages on a WordPress site are showing the error:

You don’t have permission to access /index.php on this server.

However the home page works fine, only with / at the end.

https://176.32.230.250/brokeandfameless.com/

This is the .htaccess file: https://pastebin.com/tiFHYPbP

Any ideas what could be causing it and a possible fix?

Thanks.
