Is GoAccess set as stats generator in any website and is GoAccess installed at all?
If it's not anywhere set, then this message shouldn't get logged.
And yes, it was intended to log it as an error so that the server admin doesn't miss it.
Otherwise the statistics are not being generated until this issue is fixed which could potentially result, if not noticed early on, in losing the stats for the particular period.
Yes, right, the cronjob check for the goaccess.conf takes place way to early, or it needs a pre-check if any website has set goaccess as stats generator at all. Will commit a fix for that tomorrow.
