Stopped working for me several days ago. After logging in and trying to clip a page nothing happens. I've checked logs and see nothing in particular.
Issue happens like this after providing Evernote credentials to plugin.
Open Web Page to Clip
Click on Evernote Safari Plugin Icon from the browser
A "Blank" page will flash with the title "Success"
"Blank" page closes almost immediately.
No other action.
I've attempted to uninstall and reinstall the plugin; restarting the browser; restarting the computer. Logging out of Evernote and logging back in in various orders. None of those actions resolve the issue.
Running MacOS Sierra 10.12.2, Safari Version 10.0.2 (12602.3.12.0.1), Evernote Version 6.10 (454267 Direct), Evernote Plugin downloaded from Evernote's site on 1/3/2017.
Attached a short web clip of the behavior (link below). Note, the alt text when the cursor is over the clipper icon says to log in. The credentials have already been provided.
