When swicthing versions, it is very important to read the upgrade guide (and other docs) first. Also read and understand https://blog.powerdns.com/2016/01/18/open-source-support-out-in-the-open/

Only if you think for yourself first and give complete information to the list we can maybe help you. At the moment, your messages only cause noise on the list.

Hello
I'm sorry OTTO, but I'm pressed for time as soon as I migrated to version 1.5 I encountered quite a few problems!
now I only have the problem of log (empty) and the cache which still does not work

----------Log config------------------------------
-- log all queries to a 'dndist.log' file, in text-mode (not binary) appending and unbuffered addAction(AllRule(), LogAction("/var/log/dnsdist/dnsdist.log", false, true, false))

-------------------------Cache config------------------------- ewServer({name="unbound",pool={"resolverT"},address="IP", qps=1000, order=1}) newServer({name="pdns-recursor",pool={"resolverT"},address="IP", order=2}) cacheresolv = newPacketCache(100000)
getPool("resolverT"):setCache(cacheresolv)
setStaleCacheEntriesTTL(86400)
addAction(AllRule(), PoolAction("resolverT"))

IP is not an ipaddress
ewServer is not a valid statement.

How can we possibly test out your configuration if it is incomplete?
