Configuring Plugin Settings

All the following settings are found by navigating to the LiteSpeed Cache item ( found in the sidebar when logged into the WordPress Admin for your website), or through the top-bar LiteSpeed icon shortcut – click Settings

Any settings or sections not mentioned here should be assumed to leave as the default unless you have a specific need to change it.

Cache section


The first thing you’ll want to do is navigate into the General section inside the LiteSpeed Cache settings and find the item for Domain Key. Click Request Domain Key to automatically register a key for your website with QUIC.Cloud which is a service used for some optimization elements offered through the plugin.

After clicking Request Domain Key you may have to wait a few minutes for it to update, refresh the page to check whether a key is registered yet or not. When the key is registered you should see some masked text in the key field.
