I noticed a while ago when searching for the user docs for Winter 15 that I kept getting the following error:
HTTP Status 404 - /ServiceMaxHelp/Winter15/en_us/svmxhlp.htm
type Status report
descriptionThe requested resource is not available.
I am already logged into SFDC our production and sandbox orgs on chrome. I logged out of the sandbox org just to test it, no luck. I opened a new IE window and was prompted to login into SFDC then it worked fine. I figured out what I needed without it but you did not have to logon to access these documents before, shouldn't they be easily accessible?
I used the official link from the document archive.
