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
