I am new in Magento 2x. I just want to setup email header and footer globally.
I can't locate either header.html / footer.html files in my Magento file systems as well.
Also in "Marketing/Email Templates/Add New Template/" I select 'header' template from there and try to preview or save the new template the page reloads and shows this error message "404 error: Page not found." with this URL path
I will really appreciate if some one guides me to how to configure header/footer email templates and also help me to solve this 404 issue.
