We have removed the default newsletter form and created a custom form for newsletter. I can see that it only display in the home page.
How can I show it on account create page?
I guess that you have done changes at
subscribe.phtml which is related to the footer.
But the same files do not call at my Account section it manages from this view files
So, you want to remove the default newsletter form and created a custom form for newsletter.then you have to work on this page.
