<p>If you have ever imported a Blogger blog into WordPress you probably have some posts that were originally missing a title. During the import, a title (and post slug) was created for the post that looks like a large numerical value. I believe this is the original Blogger post ID, I guess the importer needed something to use.</p>
<p>What this plugin does is replace those ugly numerical titles with the first few words of your post, like Blogger did. By simply enabling the plugin, any post that matches the ?ugly title? filter will have the title replaced by the first 48 characters of the post.</p>


Blogger Title Fix

This plugin replaces the random title given to posts that were imported from Blogger with an excerpt.

Blogger Importer

Running the Blogger Importer in PHP 7 throws the following warning:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Blogger_Importer has a deprecated constructor in /xxxxxx/wp-content/plugins/blogger-importer/blogger-importer.php on line 44

Another user reported this months ago, but it's not fixed yet.

Deprecated constructor warning

Imports posts, images, comments, and categories (blogger tags) from a Blogger blog then migrates authors to WordPress users.
