Hello Ciaran,
I installed J51_Vitality and when trying to customize, the "STYLING" sections shows nothing but a blank page.
I'll send you a Mail with administration access to my Joomla installation to info@joomla51.com.
hope you can help me quickly, corse i'm "on work" at the moment.
The Problem ist not with the free Version but there are not enough functions. Therefore i bought it-.
Best regards
Verena
