If you encounter errors with the above code use a check like this to return clean errors to help diagnose the problem.

```php
if ( ! file_exists( get_template_directory() . '/class-wp-bootstrap-navwalker.php' ) ) {
// File does not exist... return an error.
return new WP_Error( 'class-wp-bootstrap-navwalker-missing', __( 'It appears the class-wp-bootstrap-navwalker.php file may be missing.', 'wp-bootstrap-navwalker' ) );
if ( !file_exists( get_template_directory() . '/class-wp-bootstrap-navwalker.php' ) ) {
// file does not exist, return an error.
function our_error() {
return new WP_Error( 'broke', __( 'class-wp-bootstrap-navwalker.php file may be missing', 'wp-bootstrap-navwalker' ) );
}
$return = our_error();
if( is_wp_error( $return ) ) {
echo $return->get_error_message();
}
} else {
// File exists... require it.
require_once get_template_directory() . '/class-wp-bootstrap-navwalker.php';
// file exists, require it.
require_once get_template_directory() . '/class-wp-bootstrap-navwalker.php';
