Hello, SpaceX,
Unfortunately, we do not work via TeamViewer.
Please follow our recommendations:
1/ Downgrade the PHP version on your site to 7.4 or 8.0. Check Theme Options then.
2/ Disable all 3rd-party plugins, that are not bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins, and check if the problem is solved.
Let us know the results.
3/ Would it be possible for you to disable any restrictions by country?
Kind Regards,
8theme team
