Hello @tobiaseichner,
Thanks for getting back to us.
However, what kind of plugin is needed to make use of it (ideally, it should be compatible with WP Super Cache)? My search in the plugin repository was not really successful.
We can’t exactly recommend or vouch for a particular third-party plugin.
However, if you want to find a plugin that is compatible with WP Super Cache and supports APCu caching, you can try using search queries in the www.remarpro.com plugin repository like “APCu caching” and also try to refine your query by including additional keywords related to your specific scenario.
Once you settle on a particular plugin, you might need to reach out the plugin authors or search in their support forums to check if there are any reported compatibility issues with WP Super Cache.
Hope this helps!
Best,
