Does a button not work, screen not updating or something seems off with a screen. It very well may be a javascript error. Modern browsers now hide these by default.

To see if there are any errors, do the following:

  • In Chrome, go to the screen in question
  • Shit + Control + i (windows) or Command + Option + i (osx)
  • Click the Console label of the new Developer tools panel that opened
  • Reload/refresh the screen (Ctrl + R or Command + R (osx))
  • do whatever you think is not working
  • look in the Developer tools panel, is there any red text?
  • if so, take a screenshot
