I read the previous posts relating to the popup not working with YooTheme templates and had odd results as the popup works when I run it on my local machine using Wampserver and Joomla 1.5.12 but not on my live site.
Assuming that I could work around this (to show the module to a friend) by using your Mint Fresh template on a single page (
login test) I find that it still doesn't work.
I have tried the default Joomla templates as well and still don't have any luck. Is there likely to be something at the domain hosting service that is causing a problem as this seems to be the only untested part of the equation
