Changes won't save

I have been the webmaster for 621016, www.bdtm.org ( 621016.toastmastersclubs.org/ ) for quite a while now. I was trying to make some basic changes:
- update our main page with our new slate of officers
- delete some old information
- move some text
I press save and then close and the changes aren't showing on the page.
I also tried pressing Ctrl-F5 to force a refresh from the server and they still do not appear.

Any advice?

Your domain has expired, you need to pay your registrar and make sure the settings are correct. Or remove the custom domain.

You need to pay attention to the error messages

621016 - I never even knew error messages showed up anywhere until you mentioned it. I'll get in touch with our DNS host and get it resolved. Thx
