Hi Graemeboy,
I recognise you as one of Glenn’s friends. There was no other plug in installed using the mailchimp, I don’t know what it was that was conflicting to be honest. Since I wasn’t getting any support in the end it was easier for me to custom code my own download box using the mailchimp embed code as a base and throwing it in a txt box on the sidebar.
Thanks for your help though, I appreciate it and understand that you guys have a lot on your plates.
All the best
Chris
