I have a problem on a wordpress website, on each product page, when I enter, an alert appears showing an error 403 Forbidden. It comes from the file admin-ajax.php In Internet Explorer and in Mobile it almost always comes out.
I can not figure out where it comes from. It can be a problem with permissions, htaccess ... but I've tried everything.
An example url: link
Thank you!
The reason for the error 403 is that it is not sending headers. Since you are making a CORS request, you can not send any custom header unless the server enables these headers by adding Access-Control-Allow-Headers to the response.
In a pre-selected request, the client makes 2 requests to the server. The first is pre-verification (with the OPTION method) and the second is the actual request. The server sends the Access-Control-Allow-Headers header in response to the preflight request. Therefore, it allows the sending of some headers. This way, your POST request can work, because the POST request is a prior request. But for a GET request, there is no pre-verification to gather the Access-Control-Allow-Headers header. Then, the browser does not send your custom headers.
A solution:
Add in your php admin-ajax.php file before printing anything with the, example:
header('Access-Control-Allow-Origin: *');
echo json_encode($resultado);
I think it's going well!
add_filter ('allowed_http_origins', 'add_allowed_origins');
function add_allowed_origins ($ origins) { $ origins [] = ' link '; return $ origins; }
-I added the .htaccess: Header set Access-Control-Allow-Origin "*"
And I updated the plugins again.
Some of the 3 resulted:)
Thanks
