I have reported this three times now over the last 3 weeks and the problem has not been resolved. This has cropped up several times over the last year and only with What’s so special about them?

Thank You.

Description of the issue:

Exact URL of the website in question:

Did the issue present with default Shields settings? (yes/no)

Does the site function as expected when Shields are turned off?

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):

Does the site work as expected when using Chrome?

Brave version (check About Brave):

It’s not easy to replicate without actually having an account. Does Turning off shields make any difference? loaded okay (without a login)

Shields have been off for this site since the beginning. The problem has been on and off over the last 6 months but about a month ago has been persistent. I have to use Firefox or Chrome to login so the problem is obviously with Brave.

Thank You.
