Hello, Sxp666,
Thank you for contacting us and for using XStore.
1/ Is it only dark-moded your web-site or others as well?
2/ It depends on browser settings and better to check it’s settings → https://support.microsoft.com/en-us/microsoft-edge/use-the-dark-theme-in-microsoft-edge-9b74617b-f542-77ed-033b-1a5cfb17a2df
3/ It is not related to the theme but to the browser, so you can just disable dark mode in the browser ( https://www.technipages.com/microsoft-edge-how-to-enable-disable-dark-mode/ ) or search for some solutions to this question in Google http://google.com/
We hope this information is helpful.
Kind Regards,
8theme team
