PHP Fatal error: Call to undefined function mysqli_fetch_all
includes/admin.inc.php on line 1188,
What's your PHP version? The function
mysqli_fetch_allexists since PHP 5.3. We require PHP 5.4 as minimum.
The cpanel says Server Information PHP Version 5.6.35
The only thing, I can think of as cause of this error, is the following notice in the PHP-manual-page for
mysqli_fetch_all: "Available only with mysqlnd." Not every installation of PHP seems to have an activeted native driver even it is the default MySQL-driver since PHP 5.4.
I will rewrite the code to use the "classic" function
mysqli_fetch_all. I hope to solve the issue that way because I found nothing else in the code that I would call suspect.
