Blank page after newsletter form submit, ?na=s attribute is added to the URL

[Ellenrusak]

Hi,
Could you please tell what can be a reason of this issue? I see a blank page after newsletter form submit, and ?na=s attribute is added to the URL. Email is not send.
Please help,
Regards,
Ellen

Hi,
I also have the same problem.

Hi, a blank page from the server is usually a fatal error: you should check the error logs of the server (ask the provider) for some fatal error: there we can find an explanation.

Please, run a test from the System/Deliery panel: the fatal error could be a problem in your mailing system.

I have the same problem, across all sites. My network error log says the following:
