I'm not sure why, but I just had to delete my local database to fix the problem. It was 7.2GB. Is that a normal size? It must have been corrupted. I figured an uninstall would do that, but it didn't.
I have over 1,000 notes and have used evernote for years. Now it lets me type in notes, create new notes, but none of it gets saved. No error messages, no thing. On the web everything works fine. I thought my local db got corrupted so I uninstalled and reinstalled. Still the same problem. I am totally baffled. This has to have happened to someone else? Thanks!
