As of July 2020 the Chrome UI has changed once again and the logging level dropdown doesn t seem to do anything now  Instead  there s a new pane to the left of the main console pane  which may have got unintentionally set to one of the restrictive logging levels   Select the top category  messages  to reveal all the logging   EDIT  EVEN THEN Chrome seems to add things to the Filter box  which again loses some logging  so you must CLEAR THE FILTER BOX TOO   Filter box is at the top of both my pics above  under  quot Network conditions quot   you can see that it has some contents about  quot urlwebpack quot  which I didn t put there

Sometimes the simplest things trip us up    Type console log in the console and check what function gets returned  If you see    log      native code    then it s something else  If you see         then somewhere down the line the native console log function was changed  Was working on a client s site today and that was the issue  If that s the case  you can either manually restore the console log function or use console dir   or console warn   instead  If you see         then there is a possibility that sometime console stops working due to some functionality you have added in your javascript  so first close all tabs restart chrome and in a new tab just typ1 console log  hi    if it prints that then it confirms that the problem is there in your script code  if not then restore the cosole log  To restore the console in new tab go to console and type delete window console it will return true after that restart the chrome and you are good to go
