What it does

Check or regenerate LiteSpeed CRITICAL CSS (CCSS) for specific pages of a connected WordPress site.

With LiteSpeed "Load CSS Asynchronously" on, a page without critical CSS renders blank until the full stylesheet loads (slow FCP/LCP), and a page whose design changed keeps its OLD critical CSS (layout shift, CLS). Purging the cache does not rebuild critical CSS; this tool does, page by page.

action: • status — for each URL: whether critical CSS exists, whether it is queued, whether the live page actually inlines it, plus the site-level reasons LiteSpeed would skip it (CSS async off, QUIC.cloud not linked, UCSS inline on, no QUIC.cloud quota, per-URL CCSS off). Read-only. • regenerate — invalidates the stored critical CSS of those URLs, purges them, re-queues them and, when the queue is short, sends them to QUIC.cloud right away (confirm=true). Up to 10 URLs. urls: full page addresses or paths ("/service/x/"). Needs Connector 0.9.3 or newer.
