Yesterday a serious bug was introduced into Debitoor that unfortunately affected all users on the site and prevented creating and sending invoices and pretty much everything else you can do.
During the day several of you reported about the issue on e-mail and in the UserVoice forums (thank you!). Around 10.30PM CET we became aware of the problem and started to actively look for a solution. At 2.55AM CET a final fix was deployed into our production environment restoring full functionality to all users.
This morning we have completed analysis of the incident and can conclude that the bug was introduced by UserVoice (3rd party feedback platform embedded on all our pages) when they pushed out a a new version of their script that conflicted with our code.
Going forward we will either remove UserVoice as a feedback platform (which we would hate to do because we need your feedback) or move the conversation somewhere else.
We apologize for any inconvenience this may have caused you.
