Hi Jay, The files I'm trying to delete are very small ones, sometimes in the kilobyte range. I started with Safari - disabled the one extension I had (1Password) and used a private browsing window to log onto Dropbox. I did not reset Safari because I didn't want to lose my history, saved passwords, etc. Of note, it hung up, with the rotating circular icon showing up, after I selected "Deleted Files" in the sidebar. So I exited Safari and restarted it, and did the same thing. I succeeded in deleting a small file entry (a folder with a few small files), without the error message. I went back to the Files section, then re-entered the Deleted Files section, and the entry was not present, so success! I tried this again, with a non private window and it still worked. I also re-enabled the 1Password extension and tried it again and it still worked. This is a mystery to me. I then tried Firefox. It doesn't have any extensions. I started it, used a non-private window and logged into Dropbox. I did not reset Firefox. Success again. Again, I don't know why it failed before - that's a mystery. So the problem appears to have been a transient one that was something on your end, or the disable/enable of the 1Password extension and the re-starting of Safari did something. I hope this helps - it appears that the problem was indeterminate.
