NimbleCache Documentation

Install and activate. That is the setup. The plugin installs its own fast path, switches caching on, and starts storing pages as people visit them.

Two things have to be in place for a cached page to be served the fast way, and the plugin puts both there itself:

1. wp-content/advanced-cache.php — the file WordPress loads before anything else.
2. define( 'WP_CACHE', true ); in wp-config.php — the line that tells WordPress to load it.

The Dashboard says whether both are in place. If your wp-config.php is not writable — which is a perfectly good way to run a site — it shows you the one line to add and where.
