After migrating to Wordpress hosting, the install.php installer opens. What went wrong?

Question

WordPress

There is a ready site on a local (Wordpress). It was necessary to transfer to the hosting, I used the duplicator plugin.
There were no errors, everything was installed without errors, the .htaccess file is correct.
At first I went to the site calmly, but after 2 minutes the site stopped working and the installer started running when I went to any page or post (url)

What's wrong?

Answer 1

It seems to have been solved, it was the browser cache. If someone encounters the same problem, just clear the cache (browser history). The site is working
