Hi, first of all I’m not sure why you are using both WP rocket and Autoptimize plugins. I think WP Rocket shall be enough. But having said that, HMWP is compatible with both WP rocket and autoptimize plugins. We have not checked HMWP along with both autoptimize and wp rocket. It could be conflict with features like new style name, minify style, new wp-content path, API Base/Query (Permalinks & urls tab); IDS (IDS Firewall tab).
