I cannot edit prebuilt demo of The7 wordpress theme.(Populer theme in theme forest)

Hi,
Hope you all are doing great.
I would be grateful if anyone out there can help me fix these issue.

I have purchased The7 theme last week. I imported a pre-built website,
**** But I cannot edit that. Anything I edit or make any change with wpbakery or other ways, is not affecting. I cannot make changes to the website.
**** I cannot save the slider after editing as well in Slider Revolution. “Ajax Error!!! error” is shown. Screenshot link: Slider-Revolution-error-problem — ImgBB, Slider Revolution system requirement: Silder-Revolution-System-Requirement — ImgBB
**** I edited the bottom footer note. But not changing.**

Overall, many things I edit are not affecting/changing at all.
N:B: I can edit few things successfully such as, logo, favicon etc.
