Received Oops! when adding new zotero acc., my zotero feed works

I have a private key for my zotero API feed with
“Allow third party to access your library” checked…
giving my 4 digits user number and the alphanumeric key

with WP 3.2 + zotpress 4.2.6 on my localhost (because I’m testing)

I had received a red Oops! message after submit for adding zotero account.
