(Archived) Failure of Evernote Webclipper to upload

[Evernotequestion 0]

My Evernote Web clipper isn't uploading my clips to Evernote. It's as if it were stuck on the uploading. I can add new clips, but it doesn't clear the old ones. Any suggestions? I've tried uninstalling and reinstalling evernote webclipper, but the problem remains. Has anyone experienced a problem like this or knows how to clear out Evernote's cache of unuploaded clips?

Firefox 16.02

Mac 10.5.8

Web Clipper 5.4

Thanks
