Silverstripe Version: 4.6.1

**What could be the reason for this: [User Notice] mysqlnd PHP library is not available, numeric values will be fetched from the DB as strings - Line 89 in vendor/silverstripe/framework/src/ORM/Connect/MySQLiConnector.php **?

_mysqlnd is enabled

Has anybody come across this or knows what could cause this error?

Sorry, for the late reply. This all happened while I was on holidays.
It turned out that the web hosting company did some changes in the configuration.
fileinfo and mysqlnd, pdo_mysql and mysqli were not present and inconsistent in version.
