Problems with Javascript

Hiho,

I’m using Kanboard, and lately I have trouble with js.
When I try to create subtasks or even new projects, no new window opens.

I get an error 500:

app.min.js?1561173783:1 GET http://kanboard.[…]/?controller=UserAjaxController&action=status 500 (Internal Server Error)

Only solution to date would be to restart the hole server

Greetings

did you check your webserver error files?
Enable the error_log on php.ini and check for php errors there.
