SSA online contest registration not working?

Anybody used SSA online contest registration recently?
Monday I tried to register for a contest, and after filling in the info
and pressing "submit", I got a blank page (tried repeatedly).
Sent an email to webmaster and received no response (couple days now).
I'm using Firefox on Windows 10 64-bit.

I've used this dozens of times before with no issues...
Anybody else had success recently?

Thanks,
Best Regards, Dave

Thanks Janine for the tip: This is a known bug in the web site;
if you don't select "class" nothing happens and it doesn't tell you why.
Odd that one has to select "class" for Seniors and Sports Nationals.
