website force to desktop mode

Hi there,

can you explain a little.
Do you want to view the desktop site on your mobile phone ?

When someone arrives at my website by Mobile he should see the website in desktop mode not in mobile mode .

You can use this PHP Snippet:

add_filter( 'generate_meta_viewport', function() {
    return '<meta name="viewport" content="width=1024">';
} );

Adding PHP: https://docs.generatepress.com/article/adding-php/

That snippet will change the viewport so the browser always assumes the screensize is 1024px.

I must say that doing this may result in a poor usability and search engines reporting mobile usability issues eg. text too small and links to close together.

where i have to add this php

I provided the document for adding php above – here it is again:
