Pale Moon forum

I'm having trouble logging into one specific webpage from my PM Portable browser. I've tried other browsers, including other FF based browsers, without any issues. Attached is a screen shot of the error message I get. I realize that the message says to contact the website, but I thought that if it was something I could fix on my end it would be easier. Any ideas, or is this specifically a problem on their end?

It is specifically a problem on their end, and you can temporarily put a workaround in place until they fix their security.
The answer is in the FAQ: viewtopic.php?f=24&t=6262

Thank you. I add the work around for now, and send them a message.
