I have seen many folks asking the same question but nowhere we found the solution . I have recently downloaded Kibana 4.2.1 along with ES 2.1.0 . I do not have any index so just tried to check the look and feel of Kibana . Now after hitting localhost:5601 I can only see a blank screen/page . I tried to navigate to the settings tab but nothing happened.
Solution I tried to implement
I was following After installation on Kibana 4.2.0 the page is blank #12 and here they recommended that issue has been fixed and 3 files have been modified .
So I changed above 3 files from here.Still situation is same.
Please suggest what needs to be done here as Kibana is not working as the way it was working in the older versions.
