Error when trying to vote for feature

Hello,

I have the following error when I try to vote for a ticket in feature votes:
XML_RPC privileges are required to perform this operation. You don't have the required permissions.

On the page it mentions:
126 unused 0 used 0 locked 66 spent

What's the problem?
Thanks

Thank you for reporting the issue. We are investigating this more deeply after holidays.
 

Thanks!

Should be working again :)
