Previously, we discovered a possible problem with Blogger and third party cookies. That could, potentially, affect all Bloggers, but only temporarily. As everybody adjusts to New Blogger, so should their computers, and the problems should go away.
But login problems, frequently looking like they might involve cookies, surface daily. New Blogger was publicised on 12/19, and two weeks later, the login problems don't seem to be going away all that quickly.
Maybe there's another problem, and maybe it involves the wording in instructions about permitting cookies.
Jordan, in login trouble - wont remember me, provides a long forgotten link to Known Issues for the New Blogger: The “Remember Me” login option will not work, where we are advised, when configuring Internet Explorer, to
...add google.com to the list of allowed sites under Internet Options > Privacy.I wonder how many folks added "www.blogger.com", rather than "blogger.com", based upon the Firefox and Internet Explorer wizards
Type the exact address of the website...I know that I become confused by that instruction.
Now, the article The “Remember Me” login option will not work specifically mentions Internet Explorer V6 as a problem, and Firefox is implied to be free from this problem. The date of that article is 9/5/2006. Firefox V2, and Internet Explorer V7, came out almost 2 months later.
FF V1.5 and IE V6, by and large, used "permit by default, deny on demand" security strategies. FF V2 and IE V7, on the other hand, use "deny by default, permit on demand" strategies, and are more likely to present a problem with incorrectly permitted cookies.
In short, for both Firefox and Internet Explorer, check your Cookies permissions. Make sure that you are allowing "blogger.com", rather than "www.blogger.com", to add cookies to your computer.
