Fix

autoload() is Fall back to traditional autoload for old PHP versions @param string $classname The name of the class to load. You can replace the function with spl_autoload_register as shown in the below steps.

We need to register to autoload functions with spl_autoload_register, this is from PHP 5.3 onwards. This function registers any number of autoloaders, enabling for classes and interfaces to be automatically loaded if they are currently not defined. By registering autoloaders, PHP is given a last chance to load the class or interface before it fails with an error.

Locate PHP file

Locate the PHP file PHPMailerAutoload.php on your installation.

Deprecated Function

Modify the deprecated function as shown below:

function __autoload($classname)
{
PHPMailerAutoload($classname);
}


To

spl_autoload_register(function($class) {
PHPMailerAutoload($classname);
});

Stop/Start

Stop and Start the Apache server.

Verify Fix

Launch the TestLink login page and login with valid credentials.

This will fix the error and TestLink UI would be displayed without any error.
