Description

Cache Interval is always 0 seconds in the localhost:3000/admin/config page when using a redis config. It works fine with ADAPTER = memory,so it may redis related.

[cache]
ADAPTER = redis
INTERVAL = 300
HOST = network=unix,addr=/var/run/redis/redis-server.sock,db=2,pool_size=100,idle_timeout=180
