Hi
Does each extension work if the other is disabled?
At the moment it sounds like a js conflict but we would need to see the error
Are you able to switch off the current extension and enable the JA extension so we can see the problem?
or can we switch off the extension, test it and add any errors you see from the browser console?
I'm conscious the site is live so don't want to cause any potential problems with any client
Cheers
Paul
