This solved it thanks.
First step is exactly in "account summary" - "Evernote Web"
Second in "personal settings"
Very annoying and a waste of time having to figure out all this.
It happens on chrome, which is what I have been using for years. On desktop, which I do not like using, seems to be fine. If this is not resolve will move my notes somewhere else.
Evernote is currently unusable and it is getting fustrating. Every time I try to edit a note the note dissappears and I get the following error with blanc screen.
