Hello,
Please add this code to the functions.php of the child theme:
function basel_sidebar_login_form() {
$account_link = get_permalink( get_option( 'woocommerce_myaccount_page_id' ) );
if ( ! basel_get_opt( 'login_sidebar' ) || is_user_logged_in() || ! basel_woocommerce_installed() ) return;
?>
<div class="login-form-side">
<div class="widget-heading">
<h3 class="widget-title"><?php esc_html_e( 'Sign in', 'basel' ); ?></h3>
<a href="#" class="widget-close"><?php esc_html_e( 'close', 'basel' ); ?></a>
</div>
<div class="login-form">
<?php basel_login_form( true, $account_link ); ?>
</div>
<div class="register-question">
<span class="create-account-text"><?php esc_html_e( 'No account yet?', 'basel' ); ?></span>
<a class="btn btn-style-link" href="<?php echo esc_url( add_query_arg( 'action', 'register', $account_link ) ); ?>"><?php esc_html_e( 'Create an Account', 'basel' ); ?></a>
