After upgrading wp (3.9.2 now) there’s this error message, after submitting an email address in the Newsletter widget :
The document name you requested (/index.php) could not be found on this server. However, we found documents with names similar to the one you requested.
/index.html?nm=error&nk=1-c6040e5010 (common basename)
(although the submission works, the email is registered)
thanks for your great work !
The error says me nothing, the multiple choice is not something related to Newsletter. Check the subscription steps panel, the address you reported to me “/index.html” come from that panel, or it should. I think the update changed something in your installation…
