It seems you are using this plugin: https://github.com/happy-se-life/kanban
Quickly skimming over the code, it seems that store quite a lot of data in the session (which in turn gets stored in a signed cookie by default). Depending on the amount of data in your projects or other configurations, this can quickly overflow the amount of data which can be stored in the session cookie.
However, as this behavior seems to be caused entirely by the plugin, there is nothing we can do about this here. Please contact the authors of the plugin instead.
