+You're using a cache store `#{Rails.cache.class}` that does not support
+"recyclable" cache keys, also known as "in cache versioning". To
+fix this issue either disable "recyclable" cache keys by setting:
+
+    config.active_record.cache_versioning = false
+
+Or switching to a cache store that supports this functionality:
