I've used a plugin called WP all-on-one migration to migrate my website. I've also saved the permalinks twice, as instructed after the importation.
The default permalink setting works fine, but any other permalink setting results in a 404 error code (except for the home page).
Already tried the following:
1. Saving the permalinks twice (as instructed after importing by the plugin)
2. Rename old .htaccess file, let the site automaticly create a new one
