Hi,
Regarding your issues:
1. You have to translate your theme (use i.e. Loco Translate plugin) or if you are using a child theme you can change it directly from Fest/layouts/header.php file - please edit this fragment:
- Code: Select all
<?php echo __('Register Now', GKTPLNAME); ?>
2. You can add custom URL for this button, please navigate into Fest -> Template Options -> Features tab and "Register button URL" option.
3. You have to create a form with this feature. Try to use i.e. Contact Form7 plugin.
