Splunk Enterprise

Splunk server is running in the server but why GUI is not showing and giving a 500 internal server error?

Path Finder



I moved the installation Splunk folder by mistake into another folder because Splunk stopped working. Since, I had moved the folder to a different location, tried to copy it back but the copy failed and became a partial copy. So I upgraded to the latest version of Splunk and tried to start Splunk.


When I try to start Splunk, I get the following error

Even if I don't enter anything, the Splunk server starts running but the GUI is not available and gives me 500 internal server error.

Not sure what configuration file was changed during the process.
