Error 500 everytime

    Hi there.
    I just installed WordPress on my Ubuntu 20.04 VPS with 4GB RAM.

    Everytime that I change something, activate a plugin or just update permalinks, the website goes in error 500.

    What I have to do to fix this issue, is upload the WordPress core files again and then the website comes alive.

    How can I avoid this?
    I already increased the PHP limit to 3000M.

    Any number of things can cause this.

    Please check your web server logs to see exactly what is triggering this 500 internal server error, and then we can help you fix it.

    I tried to install the same backup also in localhost, using XAMPP.
    Just visiting the website 2-3 times I get this error:

    Fatal error: Uncaught Error: Call to undefined function wp() in G:\xampp\apps\wordpress\htdocs\wp-blog-header.php:16 Stack trace: #0 G:\xampp\apps\wordpress\htdocs\index.php(17): require() #1 {main} thrown in G:\xampp\apps\wordpress\htdocs\wp-blog-header.php on line 16

    Also this error:

    I analyzed the errors and I found that these calls are causing the error:

    send_origin_headers();
nocache_headers();
wp();

    What can I do?
