Cannot edit agenda in Administrator edit mode or as a member in member mode.

Logged in as Admin in Cranberry Area Toastmasters Club 9843,  The Agenda cannot be edited.  Logged in as a member and the Agenda
for September 20, 2022 cannot be edited.   

I signed in as the site admin and can see the edit pencil.
and I was able to click save after editing.
 

Now I cannot login at all as Admin.

What browser are you using?

Have you clicked the reload link at the bottom of the home screen?

Please be precise.

What error as you seeing?
What user are you using for the admin?

There was no error.  I was blocked from logging in, period.
This issue happened today for the first time in many years. 
We do not tamper with this software.
I always use the same browser, AVG. 
I changed to Google to see if your suggestion to change browsers worked.  It was a little different at login (did not display my name) but everything worked. 
LOOKS LIKE YOU ALL MADE SOME CHANGES.  I did not.  Anyway I am OK for now.
