Hi all,

I am trying to call the new attachment_manageattach api method with following parameter and sign string

contenttypeid
postid
editpost
forumid
threadid

signString:
api_m=newattachment_manageattach&contenttypeid=1&editpost=0&forumid=327&posthash =343e2988175af9505d45e3cd60143e20&postid=0&poststarttime=1342773012&threadid=754 302&upload=Upload

Response:
errormessage = (
"nopermission_loggedin",
abcd,
left,
"api=1&",
"1342861735-aa3ab722d24c711d2fe88c497e85e1e800887d7f",
index
);

I have logged in before calling this api in post method.

Please give some solution to get this work.
