Product version:
3.1.0

Is there any resolution to this error?

i don't see any errors in that log output, just warnings about things in the config file which are no longer used by recent v2.2.x releases.

though it would probably be good if those old config options weren't set anymore / changed to the current config values than what the older 2.0 releases required (which is not officially supported by SHOUTcast now - only v2.2.x and newer DNAS are officially supported).
