Support » Plugin: W3 Total Cache » Multiple sites – same redis server, same wp db prefix

  • Looking to move a bunch of sites from https://wordpress.org/plugins/redis-cache/ to W3TC while using the same redis server. I have installed and set up w3tc, but there does not appear to be an analog to redis-cache’s WP_CACHE_KEY_SALT which is, by definition

    Set the prefix for all cache keys. Useful in setups where multiple installs share a common wp-config.php or $table_prefix, to guarantee uniqueness of cache keys

    All of the sites use the same DB Prefix (I’d prefer to leave it this way) — is there any way to guarantee that caches do not overlap for different sites? Would I use different Redis DBs?

    Thanks

    Hello, First of all, sorry for the late response.

    wpdbprefix. not supported at the moment but it will be the next release
    If you are a Pro user we can send you the patch. If that’s the case before the patching, please make sure to update W3TC to the latest version as a lot of fixes have been applied.
    Best Regards,

    Marko
