Console.log and debug not printing, only return undefined. Why it can be? I've tried to re-install chrome, but it doesn't help.

Here is screenshot from chrome's main page, so functions are not redefined in some code

Click “Default levels” and make sure that "Verbose" is checked. By default it is only set to show Errors and Warnings

I came here with the same problem :/

For completeness: In the current version of chrome, the setting is no longer at the bottom but can be found when clicking the "Filter" icon at the top of the console tab (second icon from the left)

As of today, the UI of developer tools in Google chrome has changed where we select the log level of log statements being shown in the console. There is a logging level drop-down beside Filter input box. Supported values are Verbose, Info, Warnings and Errors. The default selection in the drop-down is Info.

Any log whose severity is equal or higher will get shown in the Console tab e.g. if selected log level is Info then all the logs having level Info, Warning and Error will get displayed in console.

When I changed it to Verbose then console.debug and console.log statements started showing up in the console. Till the time Info level was selected, they were not getting shown.
