I think this is caused by a javascript error on their site - more info on the Evernote Forum - please drop by and leave a message (and open a support inquiry, too) so they might fix the problem!

BTW, I installed qvernote 0.5-5maemo1 a long time ago, but it's so buggy (creates multiple copies of notes, creates blank notes, does not sync some notes, ...) that I just gave it up. It's a pity, since it has a nice interface and would be a terrific app (if it worked well)...
