I’m getting a very unpleasant error in the UI. I configured the “ I believe it’s causing the problem. I’m running the 2.1.3 UI.


Often, when a user logs in, he will get the following error message(see screenshot). If he clicks on any link a few time it usually comes back. This screenshot was made using my sysadmin user, but it will do the same thing using a standard user. I tried looking in the source code using the stacktrace (see below), but didn’t get anywhere.


Is it fixable ?




PS. Chris had a fix for me when I first tried a required group (it’s running now), I don’t know if it’s related or not :

Looking in the logs, I see the following :
