This is a sample page for you to view.

The booking form has been working perfectly inside an iframe on the website until recently, but now it's being blocked at your end.

Here is the exact iframe code I'm using:

<iframe src="https://my.workshopsoftware.com.au/bookings.html#/ZecAutomotive?token=fd94q0" width="100%" height="960px"> </iframe>

Inside the iframe your code throws this error:

SecurityError: Failed to read property 'search' from 'Location'

because it attempts to read:

 parent/top.location.search

or another cross-origin frame’s:

 location.search.

window.location.search

or if you need data from the parent use:

postMessage
