I need some help. I did install everything correct and all works, I can send test emails and the entire subscription process works perfect BUT i cant create any newsletter. when I try to create one I can select a theme but get in the preview windows already a ERROR “Sorry! The requested page doesn’t exist!”. File not found! If I continue to click on edit the entire frame/site changes and I get a 404 “Sorry! The requested page doesn’t exist!”
What could this be? I am sure I installed the plugin correct. I would be happy if somebody can help me out since the plugin seems to be great but I have no idea what is happening.
