Thank you for your feedback @wervil. 🙂
I didn’t know you did a lot of work. However, you don’t have to redo all the work you’ve done as you can easily make a backup of your website to make sure you don’t loose any data. This way, after the reset of your website and the installation, you can import your content and custom style.
As I told you, our best guess was that something went wrong during the import. If this is indeed the case, it’s recommended to address and fix the issue right now as it might lead to other problems in the future. This is why we really suggest you to reset your WordPress database using WP Reset (https://wordpress.org/plugins/wp-reset/) and start fresh with our setup wizard.
Note that if this issue is not resolved with a new install of your website, you can easily install your entire backup.
I’m waiting for your feedback. 🙂
