Object not localized!

Good afternoon.

I have downloaded the files from my web page to perform local tests before uploading them to the real web, and I have also downloaded the database by exporting it from my browser.

My problem is that if I go to the home page of my web in local I get access perfectly, but if I try to click on the menu to access a page I skip the error

“Object not localized!
The requested URL has not been located on this server. The URL of the page you have submitted seems to be wrong or obsolete. Please report the error to the author of that page.

Error 404
saez-wp.local
Apache / 2.4.29 (Win32) OpenSSL / 1.0.2l PHP / 7.1.11 ”

The previous version worked perfectly, the only change I’ve made has been to update the WordPress version to the latest available version.

Before making changes to the real web, I do them locally and analyze their impacts on the web. Before updating WordPress I did it locally and did not give any problems and, as I made more changes in the real one, I downloaded the FTP and the database to have the changes also in local but I have found this.

Could you give me a hand with my failure ?.

I use XAMPP to mount the web locally and I have both the database and the “wp-config” correctly configured.

Thank you.
