Trouble with routing

My application is up on staging.researchstudyonline.com. When my program executes a link to staging.researchstudyonline.com/index.php/Configure/xxx the page does not forward. It remains the same. 

So then I typed staging.researchstudyonline.com/index.php/Configure/xxx into a incognito window. I get the same thing. The routing is not working. 

How can I debug this? I first thought it was the way aws was setup, and then I thought it was something to do with Okta, but I don't think that is the issue, either.

That only leaves codeigniter or chrome as the problem.  Somehow the browser, chrome seems broken. Now I am using an older copy of Chrome and I get popups that I need to update it. I have tried updating it but it fails. 

Could this be a chrome/ci3 problem? How can I debug this?  Perhaps I should try a different browser? I have a debugger running so I could step into the ci3 routing with it. Any recommendation?
