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

<p>BtW Importer is a powerful yet simple migration tool that helps you seamlessly transfer your content from Blogger (Blogspot) to WordPress with minimal effort. Whether you’re a casual blogger or managing a large archive, this plugin handles the complex parts so you don’t have to.</p>
<p>With just 3 steps, BtW Importer lets you upload your .atom file from Google Takeout and automatically imports your posts—images, links, formatting, and more. It also enhances your content by downloading embedded images, replacing Blogger URLs with WordPress-friendly links, and setting featured images based on the first image in each post. Plus, you’ll get real-time progress feedback so you can watch the migration unfold with confidence.</p>
<p>Designed to be fast, reliable, and compatible with WordPress 6.9+, this plugin streamlines the process and saves you hours of manual work.</p>
<p>Notice: Nginx-based server maybe slower when importing content than Apache or Litespeed. If you’re using Nginx-based server, it’s recommended to import blogspot content in wordpress localhost, then upload to hosting or server.</p>

<li>Import content based on post type  </li>
<li>Keep external embedded content  </li>
<li>Posts or Pages date sync as date in the .atom file (e.g. your Blogspot post published on 2022/02/02, then the post in WordPress also 2022/02/02)  </li>
<li>Categories added or use existing category based on .atom file  </li>
<li>Only Blogspot/Google images downloaded, others external (saving your hosting storage, especially if you use external CDN)  </li>
<li>Only download original size images (avoid duplicated)  </li>
<li>Automatically add 301 redirect from Blogspot permalink to new WordPress URL to keep your SEO (only for post with <code>/YYYY/MM/slug.html</code> format)  </li>
<li>Redirect log page to check list of redirection has been made, also option to clear redirection logs</li>
</ul>
<h3>Note</h3>
<p>Make sure to check your content after you import contents. Also, this plugin doesn’t overwrite current post or pages, so if you’ve imported posts or pages and want to import again, kindly delete the previous imported posts, pages, and images.</p>
