Webflow site displays - Test Mode

Hello,
I have hard time solving this issue,
The published site displays - “test mode” box - image attached

How can I disable/hide this box?
Thanks

Seems something added by Memberstack, because when you disable it the button doesn’t appear

Thank you, that solved it!

How can we disable the memberstack from webflow?

I have the free version of the Combine Library installed on my site. When I publish it still says “Test Mode”.

How do I get rid of it?
