Solution to solve

Add this into your functions.php in your theme.
You can access from Apperance –> Editor
Then you try to to put this code to update the file.

function _remove_script_version( $src ){
$parts = explode( '?', $src );
return $parts[0];
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
