I have an issue with CORS policy. The request to retrieve URL is being blocked. I tried everything (Access-Control-Allow-Origin: * in .htaccess, theme's function.php, theme's header and wp-config.php file as well) and nothing seems to work. It works perfectly on localhost though.

Here's my JS AJAX script:

$.ajax({
        type: "POST",
        url: Theme_Variables.ajax_url,
        data: ({
            action: 'myaction',
            postID: postID, 
            price: price,
        }),
        success: function(response) {
            response = response.slice(0, -1);
            console.log(response);
            $('.Link').prop('href', response);
            //window.location = response;
        },
        error: function(errorThrown){
            console.log( 'error' + JSON.stringify(errorThrown));
            
        }
    });

The error I get is: Access to XMLHttpRequest at '' (redirected from '.php') from origin '' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header has a value 'null' that is not equal to the supplied origin.

Can anyone help? It would'nt be strange if it didn't work in localhost, but it does...

Reset to default 1

The problem was that the PHP AJAX function was redirecting to another page, which caused these issues. I decided to just generate a link instead of redirecting.
