When trying to turn on auto-update I get the following error:
The define(‘WPLANG’, ”); constant code was not found in your wp-config.php file.
The WP Automatic Update tool uses the WPLANG constant code as a marker/placeholder for where to add the WP Automatic Update code in your wp-config.php file. You will need to manually add the WPLANG constant code in your wp-config.php file for this tool to work. Open the wp-config-sample.php file to get the WPLANG constant code to add in your wp-config.php file.
But there is nog WPLANG contant in wp-config-sample.php, it has been depricated in2014 (see for example https://github.com/WordPress/WordPress/blob/master/wp-config-sample.php). Please advise.
