We suggest that you use:
you have a static website;
you are not using WYSIWYG redactors;
you don't have too many background images.
- The backend mode, if:
you have WooCommerce website;
you use Elementor;
you have a lot of content on each page.
Once you have customised your configuration (meaning you chose what best work for your website), you need to refresh the cache to see the changes.
Please note the following:
- If you use the backend mode - you can check in the Admin section -> Gallery, that your images are prefixed with your token.
