    Hi,

    In class-gst-woocommerce-addon.php, there is a blank line before the opening <?php tag. This outputs whitespace before WordPress can send headers and causes errors like:

    Cannot modify header information – headers already sent by (output started at …/wp-content/plugins/woo-gst/class-gst-woocommerce-addon.php:1)

    On a client site this caused a blank white page, prevented admin/login from working properly, and also interfered with WooCommerce cart/session behavior.

    I found this was already reported here about 6 months ago, and the reply said it would be removed in the next update:
    https://ww.wp.xz.cn/support/topic/issue-with-product-export-caused-by-blank-line-in-one-of-the-file/

    For now, I patched the file manually by removing the blank line before <?php, and the site started working again immediately.

    Could you please release an update that removes the leading whitespace before the opening PHP tag in class-gst-woocommerce-addon.php?
