We don’t use WordPress built-in importer as explained in our previous article, so this issue never affected our service or our clients.

But we really felt bad for fellow bloggers who were trying to do this on their own. So today our team decided to give some time to fix the issue.

The good news is that, a working Blogger.com import plugin is available for download link now.

  1. If you already have Blogger Importer plugin installed, please remove it. Plugin kept above for downloading may fail to upload in that case.
  2. If you face any issues while using above plugin, please use our free support forum. We do not charge anything to answer questions asked in our support forum! ๐Ÿ˜‰
  3. If you feel that we should have added these fixed codes to wordpress.org, we tried doing so but encountered error on wordpress trac as you can see in following screenshot. ๐Ÿ™

  1. I have download and installed above pluggin. My wordpress is in local host (xampp 2.5). When I tried to import from blogger to local host, the authorization fail with error :
    Could not connect to https://www.google.com
    There was a problem opening a secure connection to Google. This is what went wrong:
    Unable to find the socket transport “ssl” – did you forget to enable it when you configured PHP? (0)
    Thank you for creating with WordPress.
