Try the code snippet below. You can add that to your theme’s functions.php file or create a custom plugin for it.
function prevent_plugin_language_file_update($update, $plugin, $language) {
// Specify the plugin folder name for which you want to prevent language file updates
$plugin_folder = 'easy-digital-downloads';
// Check if the plugin being updated matches the specified folder name
if (strpos($plugin, $plugin_folder) !== false) {
$update = false; // Disable automatic language file updates for the specified plugin
}
return $update;
}
add_filter('auto_update_translation', 'prevent_plugin_language_file_update', 10, 3);
