I'm using python 3.7.4, django 3.06, javascript and jquery on windows 7.

I'm not sure when it happens but now my console (F12 on firefox) gives me these warning:

​I was testing my code, I made some change to it but nothing related to cookies or admin and my site has a very limited use for cookies. PGADMIN_KEY and PGADMIN_LANGUAGE look like django admin cookies and I haven't touched them. jsi18n is the traslation module for django: not my code, I took it like it was.

I haven't done upgrades in these days.

I don't know what code you can need to help me.

I use this in my template (I see jquery.cookie is not more updated but even js.cookie.min.js gives the same problem):

<script type='text/javascript' src=' .cookie/1.4.1/jquery.cookie.min.js '></script>
<script type='text/javascript' src="{% static '/js/mon.js' %}"></script>
<link rel='icon' type='image/png' href="{% static 'icons/favicon.png' %}">

also this for cookies:

var csrftoken = $.cookie('csrftoken');
function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
            xhr.setRequestHeader('X-CSRFToken', csrftoken);
        };
    }
});

• javascript
• django
• cookies
• warnings
• cross-site

• 1 I also strongly suggest you load a) a newer jQuery and b) load it over HTTPS – mplungjan Commented Jul 10, 2020 at 10:14
• @mplungjan I made the changes you suggest and I read same articles but the solution isn't clear yet. The cookies pgadmin_key and pgadmin_language e from my database postgresql and I didnt set them explicitly so it's something that should be resolved by postgres developers, right? – fabio Commented Jul 12, 2020 at 19:00

similar error, but without python nor django , was solved by clearing the cookies (firefox | developper tools | Storage | cookies...) and refreshing the page.

The warnings, like said in a deleted ment, should e from the new policy about cookies. The cookies es from pgAdmin, included in PostgreSQL.

I solved upgrading to the last version of pgAdmin AND deleting the cookies stored in the cache.
