Cause

When a non-English locale is set for a domain-owning user (admin, reseller, customer), GoAccess is invoked with that locale, however FTP logs xferlog* are always with English dates, thus the error on processing such logs occurs.

This is a known Plesk bug with ID #PPPM-15549, which is expected to be resolved permanently with the release of Plesk Obsidian 18.0.82.
