    Hi!
    I’m use WordPress Multisite on my website with site-per-url mode (e.g. site.com/site-1, site.com/site-2).
    WP Super Cache plugin is installed and:
    – not enabled on network plugins page (all sites)
    – enabled only for site-1
    – not enabled for site-2

    After visiting site.com/site-1 and site.com/site-2 – two folders with cache files has been created by plugin:
    /wp-content/cache/supercache/site.com/site-1 – and its ok, caching enabled for it, and cleared when press “Delete cache” for this sub-site
    /wp-content/cache/supercache/site.com/site-2 – its not ok, caching not enabled for it, so why cache created and served for this one? Also, in this case cache files for this site is non-removable using admin panel side (

    How can I fix this issue?

    Unfortunately, the plugin has a single configuration file and when it is enabled on one website, on a multisite, it’s enabled on all of them.

    To completely disable it on site-2, you could add code to wp-config.php that checks if the URL contains “site-2” and then defines the constant “DONOTCACHEPAGE”.

    How should WP Super Cache be enabled on a Multisite? Network Activated or per site? I can’t find an answer anywhere online as to the correct/designed way to use it. Or does it do both Network Activation AND site by site basis fine?

    Thank you

    Hi there, @epgb101,

    WP Super Cache is available on Network Activated mode only for multisites. When you network activate a plugin on a Multisite, it gets activated across all sites in the network. This is usually a good option if you want all of your sites within the Multisite to share the same caching configurations, and it simplifies management because you don’t have to activate the plugin for each individual site. However, it also means that individual site admins won’t be able to alter the caching settings; only the network admin can do that.

    After activating WP Super Cache, you should be able to manage the caching settings from the network admin dashboard, which would then apply those settings across all sites within the network.

    Does it answer your question?
