We're investigating an issue which is preventing login and comment posting for some users, and hope to have a fix released shortly.

Thanks for your patience in the meantime.

The “Remember Me” login option will not work correctly in Internet Explorer 6.0. The best workaround is to simply use Firefox. However, if you prefer IE, you can add google.com to the list of allowed sites under Internet Options > Privacy.

Update, 11/15/07: This has been fixed! “Remember Me” now works for Internet Explorer.

Users posting from the Picasa application are unable to log in.

PicasaBlogThis

The initial release of BlogThis! from Picasa to the new version of Blogger in beta has the following problems that we are working to resolve as quickly as possible:

• If you are signed in as a Blogger user, sign out, and then sign back in with your Google account (to post to the beta), you will receive an error. The work around is to close the window and repost from Picasa (signing in with your Google account).
  
• There is no sign out link if you are logged in as a beta user. The workaround is to exit Picasa.
  
• Posting multiple large images sometimes results in the photos not being uploaded properly. The best workaround for the moment is to use the Blogger edit post form to upload the images.

BlogThis! is not yet supported in beta (it won't accept beta login information). This applies both to the original BlogThis! link as well as the Blogger button on the Google Toolbar.

Update (9/12): This is now being worked on.

Update (1/4): This is now fixed. The BlogThis! bookmarklet and Google Toolbar button link to a login box that accepts either old Blogger or new Blogger (i.e. Google Accounts) logins.

Logging in with an old Blogger account to post a comment on the new Blogger is giving a “please try again later” error. Until we fix this, it may work to log in first at http://www.blogger.com/login.g, and then go to the comments page on the new version of Blogger in beta.

Update, 12/18: This was fixed this past Friday.

Users who have their Internet Explorer security settings set to “High” may have trouble logging in. After sigining in, they see a “Click here to continue” link that does nothing. One workaround is to right-click on this link and choose “Open in a new window.”

When using Internet Explorer 7 (RC1), pressing the Enter key does not submit login forms on the new version of Blogger. Until this is fixed, the workaround is to click the “Sign In” button explicitly. Update, 8/20: This has been fixed.

Users who have switched to Blogger in beta will not be able to login to comment on blogs that have not switched. Commenting using the “anonymous” or “other” options will still work. Update (9/12): We have started working on making this possible, however the change is substantial and will take a little while before it is ready. Update (9/19): This has been fixed. You can use the “Sign in with your Google Account” link on the Blogger comment form to log in with your Blogger in beta account.

Users are seeing errors when posting comments with current Blogger accounts to blogs on the new version of Blogger in beta. Until we fix this, the workaround is to preview the comment before publishing. (You only need to preview once per account.) Update (9/13): This issue has been re-written to clarify the core bug and offer the workaround. Update (9/19): All fixed.
