JavaScript is ON, but web page says it isn't.

[JPReisender]

Vivaldi 5.1.2567.57 (Stable channel) (64-bit)
JavaScript V8 9.8.177.11

When attempting to post a comment, I get the following error message:
"If you're seeing this page, you probably have Javascript turned OFF in your browser. Javascript is required in order to post a comment. To turn it back ON, do the following:"

Javascript is ON for all sites. I also added the domain in "Customized Behaviors" using chrome://settings/content - but that didn't help.

I started Firefox and tested there, and had no problem posting the comment.

Any idea what's causing this error in Vivaldi?

@jpreisender Unable to reproduce here.

Try in a guest profile.

@pesala Although I was able to post a comment, the resulting page looks like something Netscape would display in 1993. It was also extremely slow to respond.

So, what does that suggest?

Upon reading the comments at the bottom of that page it would suggest a website error and is not browser agnostic so will occur on all browsers until the webmaster fixes it,

@jpreisender I'm unable to reproduce it here either. I was able to post a comment without getting any errors. If you're still seeing this message, try using a guest window or a clean profile. For more information, please refer to the Troubleshooting issues guide.

@priest72 In my original post, I mentioned that I could post my comment using Firefox. In my response to @pesala, I said that using a guest profile worked but the resulting page looked very odd.
