Issue Accessing Registration Page on Faradars.org Using Vivaldi Browser

BobbyTech

To whom it may concern,

I am experiencing an issue when trying to access the registration page on a website (faradars.org/register) using the Vivaldi Browser on my Windows 10 Pro system. The error message displayed is:
"Application error: a client-side exception has occurred (see the browser console for more information)."

I have taken the following troubleshooting steps:

Disabled uBlock Origin
Cleared cache, history, and cookies
Tried using a guest profile of Vivaldi Browser
Tested the site on Vivaldi’s Android Browser

Despite these efforts, the issue persists only on my main Vivaldi Browser profile, whereas the page works fine when using Google Chrome, as well as guest profiles in Vivaldi and the Android version of Vivaldi.

System Information:

Browser: Vivaldi 6.9.3447.41 (Stable channel) (64-bit)
Operating System: Windows 10 Pro (Version 22H2, Build 19045.4780)

I would appreciate any guidance or support you can provide to resolve this issue.

Thank you for your time and assistance.

Best regards,

@BobbyTech The images you posted shows that something blocked by Tracer and Ad Blocker or uBlockOrigin.

And check:

Sure that you had disabled in Settings Privacy use of Tracker and AdBlocking while you use uBlock Origin? Two Blockers are not useful. Use only uBlockOrigin.
Check if you have too restrictive Permissions Vivaldi Settings → Privacy → Website Permissions.
Check in internal page chrome://settings/content/siteData if you have forbidden to let pages store data on your browser.

@BobbyTech I see similar problem with errors in Chromium 128. Seems website has wrong configuration.
