First, all the program’s security setting must be the default mode. I had the same issue and it caused by the bad cache in my browser.
I will recommend you to clean your browser cache. If you don’t know how to clean it follow simple steps below-
Open your google chrome browser. At the right top corner click on three verticle dots.
Now go to settings and select advance from the very bottom of the screen.
Here need to click on “Clear Browsing Data” and choose time duration since you are having the issue.
Now click on clear data and it will delete all the cookies and cache saved in your browser.
Now try to access your mail. If still having the problem you have to reset your whole browser as factory default. Mark a comment below if needed, I will give that step too.
