http://localhost/admin/ is giving me two errors

Can someone help me with these errors?

I installed prestashop 1.7 for the first time but I'm unable to get into the backoffice.

Fatal error: Declaration of AdminDashboardControllerCore::setMedia() must be compatible with AdminControllerCore::setMedia($isNewTheme = false) in D:\xampp\htdocs\Gem\controllers\admin\AdminDashboardController.php on line 539

The problem is the cache on your xampp. Either no cache/cache misconfigured or wrong file rights set. Try to install Prestashop on a server in a secured by pasword folder.

Xampp is not the same as a live server, it's only an emulator with several errors and problems. If you don't want to install it on your server, so you can also use virtual box by installing a lamp stack and than install Prestashop. This is better than run on xampp.

Thank you for your quick answer, I will try that.

xampp in fact is an emulator. It emulates a server, but in fact it is not the same as a live server. Several settings are different.
