If your keyboard looks like the image below, it means that you have lost your layers. That can happen after flashing the firmware and sometimes if the keyboard goes into bootloader mode.
But don't worry. Every time you make a change on your keyboard, an automatic backup is created. You can find and restore your backups in the Preferences menu on Bazecor.
Click on Restore Backup and choose the backup you want.
If you haven't made any changes to your keyboard and you don't have a backup, or you want to restore the default configuration, you can download it below and restore it using the same Restore Backup button.
