Safari evernote web clipper can't login issue

For a while, I can’t use evernote clipper in Safari,  it always failed to logon with my evernote account.  The behavior is a little stranger, If you input a wrong password, it will tell you

you type the wrong password.  But if you input a correct one, there is no any response at this moment.   Sometime it will claim  timeout .   I had tried uninstalled and installed several 

times.  The problem still exists in there.   I need to switch to chrome for clip web page into my evernote.   In Today, i inspired by a article for a relative safari issue,  I tried to clean all

my cookies, Now everything works fine
