Hi,

I encountered fatal error when trying to open dev tools in Kibana:

os: windows server 2008  
version: KIbana 6.4.2  
biuld: 18010

The other functions of Kibana work as expected, but when I click on devtools on the left side bar, the normal Kibana console interface appears in just an instance and then the following error message appears:

SyntaxError: missing ; after for-loop initializer

Can someone help me with this?

Thanks!

hello,

Can you check the kibana logs as well and paste the error message that you receive there as well?

Hi,

I don't know why, but I just fixed the problem by switching from firefox to chrome. Looks like chrome supports kibana better. Thanks!
