I tried to use the Newsletter-Plugin and got the first essential problem.
Eaven I had activated the checkbox for privacy it’s not shown up on the site. When I type in an e-mailadress and press the submit-button there is a little popup far far away from the site or the form in the site.
“Bitte klicken Sie dieses Kästchen an, wenn sie fortsetzen wollen.” -> “Please click this checkbox, if you want to continue.”
But there is no checkbox, only the text “Subscribing I accept the privacy of this site.”
An other problem is the language. Some content is written in German other in English and without a correct translation this plugin is probably useless for me.
