Permalinks are set to default

When you were importing your backup into WordPress, the plugin was checking to see if the webserver supported pretty permalinks. Pretty permalinks are SEO-friendly URLs in WordPress. They include post information, categories, tags, and the URL title, allowing you to include relevant keywords in your URL.

The plugin determined that your web server did not support pretty permalinks and reset the permalinks structure to its default type.
