Pop-up script does not work 
Автор: Tamás F.Hello,
I placed a pop-up window on the https://www.tfodor.hu/aszf.html page. The script is right before the closing </head> tag. The pop-up form from Sender.net. Unfortunately, it does not work. What could be the problem?
The form's link: https://stats.sender.net/forms/aM8VWQ/view
The script: <script>
(function (s, e, n, d, er) {
s['Sender'] = er;
s[er] = s[er] || function () {
(s[er].q = s[er].q || []).push(arguments)
}, s[er].l = 1 * new Date();
var a = e.createElement(n),
m = e.getElementsByTagName(n)[0];
a.async = 1;
a.src = d;
m.parentNode.insertBefore(a, m)
})(window, document, 'script', 'https://cdn.sender.net/accounts_resources/universal.js' 'sender');
sender('73269731b16659')
</script>
I enclosed the html code of page in .zip format.
Regards, Tamas Fodor

It works on my test page >> https://findelinks.de/123test-aufklappmenue-2/seite-146.html
It takes a few seconds for the popup to appear.
The test page will be deleted when it is no longer needed.
My used Code:
<script>
(function (s, e, n, d, er) {
s['Sender'] = er;
s[er] = s[er] || function () {
(s[er].q = s[er].q || []).push(arguments)
}, s[er].l = 1 * new Date();
var a = e.createElement(n),
m = e.getElementsByTagName(n)[0];
a.async = 1;
a.src = d;
m.parentNode.insertBefore(a, m)
})(window, document, 'script', 'https://cdn.sender.net/accounts_resources/universal.js' 'sender');
sender('73269731b16659')
</script>
I copied the code from the source code, see (1)
In WebsiteX5, under "3 Sitemap", mark the page where the pop up should appear and then click on "Expert" or "Properties" (depending on the language version) at the top and insert the code before the closing </HEAD> tag, see (2) (German version)

Thanks, but as I mentioned, script is right before the closing </head> tag.
Does the script work on my test site or not?
If it doesn't work, then it could possibly be the browser.
It works.

I tested Daniels test-page. It takes some time before the pop-up shows up - but it functions.
It functions in Chrome, Firefox and Edge.
