As you can see, I did get it to work. Saving the PNG and printing do not work. I had to take a screen shot to get the image.
What is the exact problem you are having. I had to do the following:
1) Updated Java via System Preferences > Java > Update
2) Enabled Java via System Preferences > Java > Security > Enabled Java content in the browser > Check
3) Enabled Java on wordle.net by pasting your message > Go > Click to use Java > repaste message > Go
3a) Ignored the security warning because I had just updated Java 20 seconds ago by clicking "Later"
4) Then I had my Wordle. I could neither save nor print.
5) Now I have to restart my browser after disabling Java again
