Splunk Search

Why is search syntax highlighting not working in Splunk 6.5.2?

Our search heads syntax highlighting does not function for any of search commands. This is with search_syntax_highlighting = true for the user prefs. I'm on Splunk version 6.5.2.

[general]
search_syntax_highlighting = 1
search_assistant = compact
infodelivery_enabled = 0
infodelivery_show_ad_modal = 1
infodelivery_show_configure_modal = 1
datasets:showInstallDialog = 1

What I do see if I look at the browser console output is this:

Uncaught TypeError: Cannot read property 'forEach' of undefined

This case turned out to be caused by malformatted searchbnf.conf in a few custom apps, like it lacks mandatory field of "SYNTAX". - If you have the same issue I would recommend you to check if you have custom searchbnf.conf - Strangely, the small mistakes affect the whole feature to stop working which will be improved in the next version of 6.5.4 onward - it would ignore and work around the mistakes and continue to work for the other good commands.
