Not the ideal solution, but you can do as I do from time to time…
-
Duplicate your site
-
Then in the original site, select Site History from the Site menu.
-
Restore to the version that you know you need.
-
Copy the page code from that version to your new duplicated version. The screen you’ll have to fix manually.
-
Rename your original version. For example: rename mysite to mysite-original
-
Then rename your new duplicated version to the original site name - e.g. mysite
I have done this numerous times and it gets the job done.
Good luck and I hope it all works out for you
