Hi @angelofgod,
I think they didn’t release the applicable one for WP 4.9.7 since the recent one is 4.9.6. The 4.9.7 was just released 2 days ago.
Please provide your staging URL and login credentials. And yes, please backup your site too. It’s a downside of using plugin for staging, I personally recommend a staging with a separate installation.
Or please downgrade it back to 4.9.6 first, and just upgrade it once the existing issues are fixed.
Thanks!
