Okay, I have eliminated the problem of having more than one blog tied to my Blogger account by creating a new Blogger account using a different Google ID and moving the blog I want to import into WP to this new Blogger account.
But I have the same issue when trying to import — after the authorization, I receive the message:
Trouble signing in
We were not able to gain access to your account. Try starting over.
Sigh… I just want this to work and be done with it. It seemed like it was going to be such a simple process despite having to move the blog to Blogspot and create a new Blogger account, neither of which is really a big deal. But still no luck on the import into WP.
Ideas? Suggestions? Does the RSS import method work reliably well?
