Developer Tools
If you encounter an error in an online study, open the Developer tools console using Ctl-Shift-I in Windows/Chrome, Cmd-Opt-J or Cmd-Opt-I in Mac/Chrome, F12 in IE/Edge, Ctrl-Shift-J in Windows/Safari or Ctrl-Opt-J in Mac/Safari.
Select the Console tab at the top and errors item on the left to view errors.
Ignore the 404 error related to favicon.ico
Look for the error that appears on the main screen and click on the link next to Scheduler._currentTask. Take a note of the line number (305 in this case). You may need to refresh the page if the link doesn’t work.
In this case the error is a bug in the mouse store correct function which has since been fixed.
To view the output of print statements (from yesterday’s tip), select the info item from the Console tab (print() translates to console.log();).
