I have a php application that works within a wordpress page, everything works and I added the various styles and scripts with the wp_enqueue_script () function, but when I go to click any button it should activate a jQuery.ajax function which returns me some values, I get an error in GET 404 Not found. I leave below the complete error found on "inspect" via the chrome web page:

GET http://185.116.60.85/sample-page/mapshotelsms/ajax.php?opz=elenca_sms_oggi&idstruttura=745 404 (Not Found)

The function called onClick would be "elenca_sms_oggi" and takes as parameter a "idstruttura" which in this case is 745. Also if I click on the jquery used it gives me this part of the code;

try{s.send(t.hasContent&&t.data||null)}

I don't understand if JQuery is not detected or if there is some problem with wordpress. I hope I have explained myself better. Would anyone know how to help me?
