Club website admin panel freezing after 1 or 2 changes

I am updating my club's agenda will admittedly learning as I go. At first everything was going along quite smoothly then after access the Meeting Agenda Settings function a couple of times, the site began freezing until finally becoming non responsive. I have cleaned my laptop, cleaned cookies and cache and rebooted and tried from different computers and now I cannot access the club website at all.

Our site is not large, doesn't have a lot of content or any custom code added.

Also I am trying to use asterisks to prevent the profile pic from showing up everytime Toastmaster and other functions that appear multiple times on the agenda but that doesn't appear to work as it should consistently. Any advice on that would be helpful.

The server is very busy this afternoon. Keep on trying.
