It's a bug in Send.
It works if I add them from the +Add files dialog box on the send page, just not from the files page by 'ticking' the files and selecting 'send' from the menu above the file list.
This is reproducible in Chrome and IE.
Yes, there is a bug (introduced recently). The good news is that there is are two easy workarounds.
- If you get that error, simply close the dialog, go back to your Files listing, and try it again. It should work the second time.
- If you want to avoid seeing that error, just click the Send tool in the header (to the right of Files) then go back to Files. It should work now.
The issue is that with a recent change to the service. we delayed a check of your account status (Free or Paid) until you go to the Send tool. This was to make the sign-in faster. Unfortunately, we missed the case that you just encountered, much to our chagrin. We'll get it fixed, but in the meantime, the workarounds should let you get your work done.
Apologies for the inconvenience, and thanks for alerting us to the problem.
