Removing the orange bar

Hello!

I have used the plugin to create a staging version and redesign my website on it.
Once done, since it was a once in a time migration, I had my hosting provider migrate the new, staged site to the root folder. It all worked well but I have an issue:
– the orange bar has remained, which makes sense in a way since the installation was a staging one.

So 2 questions:
1. How can I make the new installation the original one (read, remove the orange bar)?
2. Are there any other parts that should be “neutralized” or cleaned up?

Thank you in advance
Julian
