Tried in two servers: Joomla 3.9.10. PHP 5.6.26 / 7.2.4. DB 5.6.33 / 5.5.5-10.2.15-MariaDB-log. Server Linux / FreeBSD
After 3.8.10 update from a 3.8.8 fresh installation in test environment.
Yes we know. In the original report and subsequent fix it has been identified that a file is being removed by the update process that should not be and that's why it is not an issue on a new install.
