Hi Vicki,
I think you have not edited the right layout.master file, your site still has the script error that would be fixed by making the correct change in layout.master. In Chrome if you right click http://www.creativestrand.com.au/ and choose inspect element, then click the console tab you can see the script errors that will be fixed by the jquery migrate plugin.
You might also check the error log if you make a typo in the layout.master file it can fail to load and then load a failsafe version and log the error.
Best,
Joe
