  • Long time WP Super Cache user here. I’ve recently started using Multisite in a big way. And I’m getting really frustrated with WP Super Cache not allowing me to disable it on a per-site basis. It intereferes with some of the WooCommerce widgets, and the only option so far is to turn it off. Apperantly W3TC honors WooCommerce’s instructions not to cache those sidebars. But even if I started using it, I’m interested to know if there’s a way to disable it per-site if there are issues?

    Also, does it have an easy “Delete Cache” button in the admin bar for when you’re working on a site?

  • Hey Tevya,

    Like yourself, a long-time WP SuperCache user. For the past several years I’ve been using WPSC on a VPS powered by Nginx. As such, I had to work really hard to get the conf files just right (this was back before a lot of folks were attempting WordPress on Nginx without Apache), of course, now there are .conf files for the pickings.

    Just this morning I uninstalled SuperCache, and plodded through the process of installing W3 Total Cache. One of the first things I discovered was that it refuses to allow site-wide activation. So, right there you’re challenge with disabling it “per-site” is actually not an issue.

    I’ve yet to turn the plugin on with any other sites on my install, but will report back here if I experience challenges.

    Oh, the plugin also inserts a “Performance” menu item in the top admin bar with an “Empty All Caches” link for easy access wherever you are in the WP backend.



    Of course, after messing about with this for a few hours, I’m not seeming to be able to do a couple of things:

    1. Get the built in minify to work allowing Smooth Slider. As such, I’ve had to disable that portion of the plugin and go back to Better WP Minify
    2. Individual activation of W3TC on subsequent subdomain sites works, but once all settings are good to go and the plugin set to overall enable, it does not appear that CDN services are working on these other sites (using domain mapping on them)

    boldlygoing, did you advance in your investigation?

    Especially the domain mapping part…


    Hey brasofilo, unfortunately, no. I’ve ended up having to split off the domains where having the cache working was important and setting those up as individual WP installs. 🙁 Sucks, I know, but at a certain point I just had to move on since support really wasn’t there.

    Cool, thanks for your feedback.
    Powerful plugin but bloody complex 🙂 🙁
