Got this just from their support;
“As per our tutorials, you can turn off settings like minimizing JS / CSS etc, try each one in turn until you see the desired look.
I would start with all the settings off, then turn on each one until you see the one that causes the issue.
Most of the time issues like this are due to the theme of not having the right file at the right time.
You might also want to check with the theme to see if any javascript files need to be whitelisted etc.”
Soooo, could it be anything within the theme before I start turning on/off the settings?
