Same situation here.     I checked the apache access_log and the monitor page is refreshing as expected.     But somehow it never sees any request.     If I send a request then click on the "Live" button again, then the second monitor window will see the request.  

I have another computer with hcl currently running.     If I copy the hcl folder from the working computer over,  everything works fine.

I also tried this one time (cant tell if it will work the next time).   Logged in as admin, clicked "settings", then clicked on all the buttons at least one.   Then suddenly it started taking request.

Basing on these 2, I guess some required files are missing when the folder is first set up.
