list building parameters can't be saved

[leopoli]

Hello!
I installed your plugin on a website http://www.larepubliquedescitoyens.org/ and it’s fine! It works perfectly and fits my expectations but… I have a major problem when I try to modify the list-building parameters: when I save, the page becomes blue, and nothing happens, modifications aren’t saved.
When I try it locally, it works fine. The trouble appears only on production server. I checked the files attributes, and they seem correct. Th point is that it happens only on this page: other functions work fine. Could you please help me find what’s wrong?
Many thanks.
L. Poli

Usually this is due to a fatal php error. Have you access to your server error logs?

Hello,
Finally, I created a “Newsletter dedicated page” (which is said to be optional), and then the problem was solved…
Thank you anyway.
