Dear.
I have check your site and I see that problem because you use Blank Layout (without header and footer) in WPBakery Settings (see atatchment). Please check your site again.
After making changes to the WooCommerce Image sizes, be sure to regenerate your thumbnails. Doing so will apply your changed image sizes to images already uploaded on your site. You can use this plugin: Regenerate Thumbnails
If after regenerate thumbnails it still not working, Please kindly send for me admin account and your problem URL via private reply. I will check details to help you.
After install and active plugin on your site, please:
1. Go to admin menu ‘Products -> Product template’ and create new custom product
2. Use shortcodes ‘WC Page Templates’ in WPBakery to build custom template
3. Then go to admin menu ‘WooComerce Settings -> Product template tab’ and select default custom template or assign template by product type.
Dear, with your problem, you can use upload file to allow user upload signature file on your form. Why you not use it ? Because with upload file the user can load signature PDF file and can’t edit it.
Dear, I check email ‘Customer note’ on your site and I not see you replase {order_note} variable to {customer_note}. Please see attachment and check again.
Dear, Please kindly update Panmail to latest version 1.1.12 from Codecanyon then use ‘Customer Note {customer_note}’ variable in Customer note email and check again.
