it may not works for everyone after I changed the code as it only applies to English WordPress site

you should change the following code to make it works(
The directory that the file located should be:/public_html/wp-content/plugins/wp-downgrade/wp-downgrade.php

change the following code(Line 118-151):
global $wp_version;
// If current version is target version then stop
if ( version_compare( $wp_version, $dg_version ) == 0 ) {
return;
} //https://downloads.wordpress.org/release/de_DE/wordpress-4.5.zip
$updates->updates[0]->download = “https://wordpress.org/wordpress-“.$dg_version.”.zip”;
$updates->updates[0]->packages->full = “https://wordpress.org/wordpress-“.$dg_version.”.zip”;
$updates->updates[0]->packages->no_content = ”;
$updates->updates[0]->packages->new_bundled = ”;
$updates->updates[0]->current = $dg_version;

return $updates;
}

function wpdg_urlcheck($url) {
if (($url == ”) || ($url == null)) { return false; }
$response = wp_remote_head( $url, array( ‘timeout’ => 5 ) );
$accepted_status_codes = array( 200, 301, 302 );
if ( ! is_wp_error( $response ) && in_array( wp_remote_retrieve_response_code( $response ), $accepted_status_codes ) ) {
return true;
}
return false;
}

function wpdg_get_url($version) {
$sprache = get_locale().’/’;
if ($sprache == ‘en_US/’){
$sprache = ”;
};
$url = “https://wordpress.org/wordpress-“.$version.”.zip”;
return $url;
}

?>
