No errors appear in logs, as it seems, this is a log for 3 clicks on add New member in project settings. The member list doesn't show, instead just a glimpse of the spinner and return to the same settings page.

I just realised that if I open in a new tab the "add New member" ctr+ New member click the window opens and I can add or remove users to the project.

Update: found the source of the problem, was related to a strict CSP policy at apache. Nothing to do with Redmine. CSP was blocking 'eval'.

Hi, I have the same issue on Redmine 4.0.4, but I don't have CSP enabled. It happens on all the browsers. Can't find the resolution anywhere. Would appreciate any hints. It is happening after upgrade from 3.4 to 4.0.
