Cannot create users KnowledgeCenter2016.

Hi all,

I'm having issues trying to create users in knowledgeCenter2016. Every time I go to the web app ->  Content manager -> Settings -> Users and hit the 'New' button to create/add a new user, a new window opens up but it never display any information, it just keep loading until it times out.

I've noticed that this only happens for 'users' since I'm able to create/modify 'User Groups' and 'User Roles' as well.

I have reinstalled the InfoShare app and ran a DBUT, everything seems to be properly configured however this issue still persist.

Could you please help me identify what could be causing this problem? where should I look at for these kind of requests/logging?

Thanks in advance.

Jose
