Hi @haseeb_iqbal

Which checkout you are using?

Please check once with default magento checkout or there may be any custom module or checkout is conflicting there.

Also make sure that you have form key in registration phtml for checkout page.

<input name="form_key" type="hidden" value="<?php echo Mage::getSingleton('core/session')->getFormKey() ?>" />
