Splunk Enterprise Indexes Screen Blank

[drd]

Hello,

I just installed Splunk Enterprise on Linux on an AWS EC2 instance. It looked like it works, I can start splunk and login as the admin user.

But if I go to the indexes screen using Settings --> Indexes the screen that appears is blank, apart from the black menu bar across the top. There is no sign of an error, just nothing - screenshot is below.

I'm new to Splunk, can you suggest where to look for the error?

Or is this a familiar error?

Thanks,

Dave
