Hi Jaime,
Many thanks for your email. So with regards to your email, I have done the following:
1. Plugins – there are no other plugins apart from Events Calendar, Events Ticket, Events Ticket Plus, Woocommerce
2. Backed up website and switched to Twenty Seventeen – this does seem to have resolved the problem.
So in this case I will try and work with the theme to see what it is that could be the cause. But since I am not that technical, I wanted to ask that if I cannot get it working with the Enfold theme, would I be eligible for a refund and license revoke?
