Frequently Asked Questions

Common questions about WP CSS Merge

The plugin builds a bundle when its first stylesheet link is being printed. If generation fails, the original stylesheets load unchanged.

External stylesheets and styles with inline, conditional, RTL, unsupported at-rule, or different media behavior remain separate to protect rendering and cascade order. Handles listed in the exclusion setting also remain separate. If another plugin filters stylesheet links or URLs, bundling is bypassed for that request so every original filter and attribute is preserved.

New bundle writes have a default 100 MB storage budget per site. At the budget, uncached style combinations fall back to original files while existing bundles remain usable. Concurrent writes may briefly exceed the budget. The wp_css_merge_max_cache_size filter can change the budget in bytes. Purge page and CDN caches before manually clearing generated CSS to reclaim storage.

Bundles are stored in a wp-css-merge directory inside the current site's WordPress uploads directory. Multisite installations receive separate site-specific directories through the normal uploads API.

No. WP CSS Merge performs local filesystem and stylesheet processing only. It does not use external services, telemetry, or tracking.

Stylesheet handles are the first argument passed to wp_enqueue_style(). A theme or plugin developer can provide the relevant handle when troubleshooting compatibility.
