Hello, Abram,
https://prnt.sc/Ux-K21U6qGQM – we can see the next js error from siteground-optimizer
In order to troubleshoot the issue you are experiencing, we suggest that you first try disabling all third-party plugins that are not bundled with XStore. You can refer to the following link for a list of included plugins: https://xstore.helpscoutdocs.com/article/36-included-plugins . Additionally, please clear the cache of your browser and check again. It is possible that one of the additional plugins is causing the problem.
Let us know the result of this test.
Kind Regards,
8theme team
