Keep Getting Logged Out as Club Admin

I log into my club's website using the admin credentials. It successfully gets me in. Then, right after making a change and clicking SAVE, it tells me I am no longer logged in. I tried this several times over several hours with the same end result. My assumption is this is an FTH-side issue, but I certainly could be wrong about that.

Club number please

Did you check error message when you save?

The error message was that I was no longer logged in. I tried a different browser a bit ago, just to see if that made a different. I also tried making a different setting change and still got the message that I am no longer logged in. 

Just had the club President log in as admin and she got the same result -- we can log in as admin, launch the admin console. Then, any action to change-and-save gives the error message that we are no longer logged in.

We need your club number to investigate.
Does your club use a private domain name?  If so make sure that you have your DNS records set up as per the documentation here:  support.toastmastersclubs.org/doc/item/dns-settings-overview

We use  metcalf.toastmastersclubs.org/ for club #4843
It worked fine in the morning the other day. Then, in the afternoon, it started logging us out whenever we hit SAVE. I just tried again and get that error message. The error message appears in a window behind a warning message about not supporting JavaScript.
