Can't upload files

Hello,

I'm trying to upload a file to my Dropbox account. When I try, it first fails outright with the message "There was an error uploading a file." If I retry, then it puts the upload into a queue, but then gets stuck there. The file is less than 1 MB, so size doesn't seem to be the issue.

I had this problem before trying to upload to a folder that was being shared with me, and when I instead tried to upload to a folder that I had created, it worked. So I figured that was the issue, but when I tried to create my own folder and upload this time, that still didn't work. I even went back to the previous folder that had worked, and it didn't work this time.

I've tried various fixes, including logging in and out of Dropbox, renaming the file to be uploaded, copying another file already in Dropbox and attempting to edit the copy (it opens up but the content is garbled), and creating a new file so I could copy and paste into it (it just goes to a blank page and doesn't finish creating the document). My internet connection seems to be fine.

Has anyone else encountered this issue? Could it be some kind of security setting on my desktop preventing the upload? That's the only other thing I can think of.
