Hello, Restorialifee,
Thank you for reaching out to us. Unfortunately, as your site is local, we are unable to check it.
We suggest that you try the following steps to troubleshoot the issue:
1. Reinstall the XStore theme and XStore Core plugin. It appears that some files may be missing. Please download the archives from this page – https://www.8theme.com/downloads
2. Test the issue on another local platform, such as https://localwp.com/
3. Check if the same errors appear on your live website.
We hope this helps.
Kind Regards,
8theme team
