While on one website everythin works perfect, on the second site whenever the newsletter profile link is clicked, part of the link is “removed” (seems like a redirect) and the error 404 (page not found shows uo):
Could you help me with this. I cannot figure out whats happening. Strangely, the other site works prefectly fine. I as well was already deactivating all plugins apart from newsletter, but this does not help.
I can find this entry in the folder /wp-content/plugins/newsletter/do
