Changing content location

I have a several wordpress sites on my hosting-server but am having an issue with a paid-theme on my root-site. Whenever I open a lower ‘child’ page the theme displays all of my photo-albums at the top of the page and not in the correct original order. (I have contacted the theme ‘developer’, but no response after several-weeks) One solution that I was pondering was to move the contents of aforesaid page to a different page on a separate branch of the site (ie say rather than https://www.example.com/page_1 to https://www.example.com/new/page_1)
Would this require ‘redirection’or much other work? (I’m trying to make it as simple and painless a process as possible)
All ideas gratefully received,
Tom
