Kanban Board not showing

[VINCENT DUPONT]

Hello

on a Jira software project, we used to work with the kanban board. This is based on a filter that returns all issues from the projet.

Previously, this worked very well (since a few months).

Today, the board does not display. We are facing a loading layout with empty columns (not real kanban columns but vertical grey bars). 

The Timeline, backlog and Reports screen do work, however. Also from thos screens we can reach the board configuration, but all changes we have made did not solve the problem

We have also created a new Kanban Board but the same issue occurs

This is occuring on that only one project.

Do you have any idea?

Hello

I've found the source of the probleme : We had changed the Issue Type Scheme and removed one issue type, but there were issues of that type in the project.

When adding the issue type back, the board appaered correctly
