if you still need the custom css to work – change at line 101 in login-with-ajax.php

//Enqueue scripts - Only one script enqueued here.... theme JS takes priority, then default JS
			if( !is_admin() ) {
			    $js_url = defined('WP_DEBUG') && WP_DEBUG ? 'login-with-ajax.source.js':'login-with-ajax.js';
				wp_enqueue_script( "login-with-ajax", self::locate_template_url($js_url), array( 'jquery' ) );
				wp_enqueue_style( "login-with-ajax", self::locate_template_url('widget.css') );
			}

				}else{ //Default file in plugin folder

				}
			}

I just borrowed it from a previous version – you could do the same thing with the JS but I didn’t need the JS
