Community Q&A
Which free WordPress caching plugin is best?
WP Super Cache is highly recommended for its reliability, while LiteSpeed Cache is preferred for sites hosted on LiteSpeed servers.
Does caching fix slow WooCommerce load times?
Caching helps, but slow WooCommerce sites often require object caching like Redis or Memcached to reduce database load on every page request.
Why did my site lose all CSS after enabling caching?
This is usually caused by minification or CSS combination settings in your caching plugin; try disabling these features one by one to isolate the issue.
Is object caching necessary for WordPress?
Yes, especially for dynamic sites like WooCommerce, as it prevents the database from being hammered by redundant queries on every page load.
