I have a problem with this plugin. I insert the newsletter in a page named "newsletter" by the shortcode [newsletter].
The action of the form in this page is:
And it redirect to:
http://my.site.url/wp-content/plugins/newsletter/do/newsletter?nm=confirmation&nk=X-XXXXXXXXXX (error 404)
It seems to be a problem with the creation of the url.
Can you help me please?
