Custom Cache Folder

Hello

We are trying to use a custom cache folder

Have added the below snippet before the # BEGIN WordPress section in our .htaccess file, as described here: https://www.keycdn.com/support/wordpress-cache-enabler-plugin

Flushed all server caches etc. but the default folder ( cache-enabler ) is still created and the custom folder is not created.

Test environment Debian 10/Buster, Apache 2.4.38, PHP 7.4.23

Many thanks
