Hello @streetlifebahrain,
Thanks for writing in! Just for future topics, self responding or bumping your post pushes it back in our Queue system so it takes longer to respond to.
What you are wanting to do requires customization of the WooCommerce My Account template files. You may need to check out this documentation first:
You will need to copy: wp-content/plugins/woocommerce/templates/myaccount/form-login.php and upload it to your wp-content/themes/x-child/woocommerce/templates/myaccount/form-login.php. You will need to edit this file and rearrange the display of the form so that the Register form will display first.
Note: We are unable to provide support for customizations under our Support Policy. If you are unfamiliar with code and resolving potential conflicts, you may select our One or Care service for further assistance.
Best Regards.
