Hi Glenda
Ouch! Certainly I'd suggest the reload Safari and Log out of CleverNote steps to try to get you back on track.
We've been hearing of a number of AdBlock related problems. If you look, we use "/ad/" as part of the URL, and that seems to cause AdBlock to interfere. So that's a possibility.
What would be really useful would be any messages in your Javascript log. Here are some notes on how to enable this...
"By default the developer tools is not turned on, so make sure you go to Preferences -> Advanced -> Show Develop Menu in Menu Bar. Then you can pull up the console with Command+Option+C. (That shortcut obviously assumes Mac, not sure the PC shortcut, but it's in the dropdown as well)"
If you could enable that, reload the page, and then paste the console log output, we would be more than grateful.
kind regards
