Captcha validation: progress bar hangs when captcha fails

Hello all,
I applied a captcha to a bootstrap 3 form.
I added the WA progress bar server behaviour.
It all works, locally.
But when I publish it on the production server there is a problem: if the captcha is not correct, the progress bar shows forever.
Please note that if the captcha is correct the page works normally and submits correctly.

You can see the live page here: https://www.landgame.eu/il-mistero-delle-12-perle/puntata-1/parte-3.php
The form will open when you click the " UN TUO COMMENTO?" button.

I've recreated the page multiple times but the result is the same: it works locally but not online.
The page is pretty simple but I cannot spot the problem.

As a side note: the original page was using bootstrap validator but I disabled it because it doesn't work well with WA Progress bar.

I add here the php page along with the WA folder, in case someone can help me.
TIA
tony

I just tested and the page worked for me. Maybe try clearing your cache?

Hello Ray,
I just tested it on a new system (so, I can exclude a cache problem) and it doesn't work.
Try this: add some text to comment field, enter a wrong code in the chaptcha field and check privacy checkbox. If you try to submit the form the progress bar appears but keep displaying and nothing happens. No error will be thrown.

When I track the submit in the browser's console... I see that the page is requested in http:// format... That is being blocked as mixed content.

I'm not sure where or how the url is changing to http:// instead of https:// which is what is causing the issue. I'd have to debug this live with FTP access to determine any more.

Maybe try updating line 14 from:
$WAFV_Redirect = "";

to:
$WAFV_Redirect = "https://www.landgame.eu/il-mistero-delle-12-perle/puntata-1/feedback.php";

Hi Ray,
you rock!
It's definitely the server validation redirect.
Me too was searching for an http:// call without finding one.
But changing the redirect to full addess with https solved it.
Perhaps there is something to correct in the WA server validation files? I just installed DB2 latest version downloaded from WA website.
What else could it be?
Ciao

Some sort of server configuration issue... When you redirect to "page.php" it goes to the http:// version even when you are on https://. I've never seen that happen before, so I think it is a server issue of some sort.
