It is not recommended to run WP Lightning Load side by side with other caching or front‑end optimization
plugins. While it may seem beneficial to stack multiple plugins to “double” your performance, in
practice overlapping features create conflicts that are hard to debug and often produce worse user
experiences. Multiple plugins that write caching headers or manipulate .htaccess can
overwrite or duplicate rules, leading to unpredictable cache behavior and difficulty purging or
refreshing content consistently. Similarly, when more than one tool attempts to minify, combine, or
defer the same CSS or JavaScript files, you can end up with broken layouts, missing functionality, or
duplicated inline code that is painful to trace.
Plugins with lazy loading, HTML compression, or Google Fonts inlining may also step on one another’s
transforms, causing flicker, layout shift, or blocked rendering. Performance plugins are particularly
sensitive to execution order, environment differences, and theme or builder integrations. The safest and
most effective approach is to choose one comprehensive solution and configure it well. If you are
migrating from another plugin, fully deactivate it, clear caches, and remove leftover rules before
enabling WP Lightning Load features. This avoids stale files, mixed transformations, and competing logic
that make troubleshooting unnecessarily complex.
In short, pick a single optimization stack and tune it carefully. WP Lightning Load provides caching
headers, minification, defer controls, lazy loading, image conversion, critical CSS, and more—sufficient
to optimize most sites without additional performance plugins. Reducing moving parts minimizes surprises
and makes maintenance far easier over time.
