If you have a computer, you have the ability to serve such a service. You just need the knowledge of how to do it.
It makes no sense troubleshooting an old version of kanboard, the issues most likely have been addressed at this point, and if not, any changes made would do you no good, until Framasoft updates their KB version to serve you.
I tested this option on https://projects.nachostudio.ml/ and also with Framaboard (using 1.2.11 version now) but it doesn’t work. I can’t validate the choice.
I can enable this option, it works, but when the dialog box appears, users can’t save their choice (“save” or “cancel” doesn’t appear on web page) ? As a result, the situation is blocked.
I’ve submitted a fix and it will be available on next kanboard release.
You can also run kanboard from latest (master) and don’t need to wait for releases.
You will have to wait framaboard to update their kanboard instances to get the fix.
I just tested on framawork and the workaround works fine.
