Caches the output of your menus. That’s it 😉
Specifically, it caches the output for every unique page. This allows the menus to retain the current/parent/child classes unlike most other menu caching plugins.
Why should I use this plugin?
If you want to cache your menu content obviously, but specifically if you want to cache your menu content and keep the current/parent/child page classes working. Most menu caching systems do not cater for keeping the various classes working, whereas this plugin does.
Why shouldn’t I use this plugin?
You should not use this plugin if you have a huge number of posts/pages on your site. The plugin caches each menu individually for each post. This can result in a huge number of cached menus on some sites, which could actually resulted in a slower site in those situations. It could also overload your object cache backend if it has insufficient memory to store them all.

- Upload the complete ‘menu-cache’ folder to the ‘/wp-content/plugins/’ directory OR install via the plugin installer
- Activate the plugin through the ‘Plugins’ menu in WordPress
- That’s it. The plugin is now working 🙂

- Can I use this plugin to cache my widget areas too?
- How long are the menus cached for?
They are set to cache for one hour by default. You can change this by creating an extension plugin which extends the main plugin class and modifies the cache_time variable.
- Why isn’t this baked into core WordPress?
Because it is not a good idea to cache a fresh menu for each page on some websites. If you don’t have many pages, then this is a perfectly acceptable way to handle menu caching. But if you have a large site with many pages, then there may be too many menus to efficiently cache.
- Where is the options page?
There isn’t one. Just activate it and it should start working immediately. There is a cache purge button on the plugins page, but this should not be needed in normal usage.
- Should I use this as well as WP Super Cache or W3 Total Cache?
Maybe. Those plugins do full static page caching. Caching your menus is only useful if your visitors are able to bypass the full page cache (this usually occurs when people comment or are logged in).
- Your plugin doesn’t work!
It does work. If you think it is not working for some reason, please let me know why. Just because you can’t see any changes on your site, or it doesn’t “feel” faster does not mean that it is not working. In fact if you use the plugin incorrectly, your site could actually load more slowly than before. Caching is a complex thing and it can backfire on you if you don’t do it right.
- Doesn’t an object caching plugin do this already?
Not quite. Object caching plugins are able to massively reduce the load created by WordPress menus, but not entirely. This plugin takes it a step further and caches the entire menu. Using the menu cache plugin in conjunction with an object caching plugin makes complete sense and is highly recommended for maximum performance.
- Does it work in older versions of WordPress?
Probably, but I only actively support the latest version of WordPress. Support for older versions is purely by accident.
- I need custom functionality. Can we pay you to build it for us?
No, I’m too busy. Having said that, if you are willing to pay me a small fortune then I could probably be persuaded. I’m also open to suggestions for improvements, so feel free to send me ideas and if you are lucky, it may be added for free 🙂
