Are you using this on a multisite install or multiple WP installs on the same system? If the latter, is the cache key prefix different? I’m running this on a multinetwork multisite and haven’t had trouble.
This plugin is compatible with Multisite installations. You can read more about the cache key prefixing that Brandon mentioned here: https://ww.wp.xz.cn/plugins/redis-cache/other_notes/#Configuration-Parameters
Hello there.
I’ve found the same problem myself, I have not a one multisite but many wp installations under same server.
Setting WP_CACHE_KEY_SALT in wp-config.php of each of them seems to work at first, this is the “Settings > redis” screens shows the key that as been set, but when proceed to enable the cache and check using “Show Diagnostic” it shows key is empty
Any ideas ?
Mmm, sorry guys, seems I found the problem, and it was all on me.
Apparently I added the define() for WP_CACHE_KEY_SALT in the wrong place of the wp-config.php (at the very end) and that seemed to caused this effect of apparently showing ok at first but then not working when enabling.
Maybe my stupidity will help some other silly goose out there 😉
Cheers !
