I investigated this a little further and found that your suggestion about the theme having something to do with this was correct. It appears in my Avada theme I had Google Maps enabled. This was causing conflicts between the theme and your plugin. I have disabled google maps inside Avada theme and now your plug-in is working just fine.
Many thanks for your quick responses to assist me.
