Replacement is on its way.
We have been a long time user of FlySpray, a simple to use bugtracker. Especially where end-users have access. However, it looks like the project is dead, the website is down, and under modern PHP version there are tons of issues. We fixed a handful of them, but under the current circumstances it does not reports the dates correct anymore and the error messages are annoying. We are currently working on a replacement, but for now, it is what it is. Sorry for that.
