This code snippet replaces the standard error messages like ‘Incorrect username or password’ with a custom message shown on the WordPress site, when a user tries to log in with incorrect login credentials.
function ts_custom_login_error_message($error) { // Your custom error message $custom_error_message = "Oops! Something went wrong. Please check your credentials and try again."; // Replace the default error message with your custom message return '<strong>' . esc_html($custom_error_message) . '</strong>'; } add_filter('login_errors', 'ts_custom_login_error_message');
