Hi Stefano,
the link looks like the example by Kimosogi. I haven’t any problems with links without the full url.
Step 1 subscription: It works. Link in the E-Mail looks like this:
http://myurl.de/wp-content/plugins/newsletter/do/confirm.php?nk=15-f2533de1c6
Step 2: “Welcome-Page” on the Blog opens
Step 3: E-Mail-Confirmation with possibility to unsubscribe ({unsubscription_url})
Looks like this:
Unsubscribe from Newsletter: myurl.de/wp-content/plugins/newsletter/do/unsubscription.php?nk=15-f2533de1c6 click here <http://myurl.de/wp-content/plugins/newsletter/do/unsubscription.php?nk=15-f2533de1c6> .
Change your Data: click here <http://myurl.de/wp-content/plugins/newsletter/do/profile.php?nk=15-f2533de1c6> .
Step 4:
Klick on unsubscribe Link. I’m signed out from the newsletter-list. The Blog opened a Site with no known Page: ERROR 404 – Page not found
I think it’s only a simple mistake. But I can’t find it.
Bye,
Katerjerry
