Hi @kingbolo, thanks for asking! 👋
You can have xSpeed Cache and WP-Optimize installed on the same site, but we don’t recommend enabling overlapping caching or optimization features in both plugins at the same time. Running two page caches, minification systems, or similar optimizations together can create conflicts or duplicate work.
If you want to use xSpeed as the main performance solution, we recommend disabling WP-Optimize’s caching and other overlapping optimization features. You can still keep WP-Optimize active for any specific feature you need from it.
For WooCommerce, xSpeed also takes care of dynamic pages like Cart, Checkout, and My Account, so these shouldn’t be cached like regular pages.
If you notice any conflict or unexpected behavior, please share the details here and we’ll be happy to investigate and help you configure it properly. 🙂
