You can access the Console with Ctrl-Shift-J (for Windows) or Command-Shift-J (on Mac)
You can also access it from the Browser Menu (upper right corner of the window) and then:
> "More Tools"
> "Developer Tools"
It's most effective if we can capture only the errors as the issue occurs.
Clear the Console by right-clicking in the Console: > "Clear console," as well as showing errors only.
Then try to replicate the issue. This gives us the best chance of capturing the exact error that's occurring.
Any errors will be in red. If you could take a screenshot of any errors you see, this will help us troubleshoot the issue more quickly.
