Hi Ciaran,
I attempted what you suggested,
I re-installed the module from my Boutique Boutique Install files folder - No success
I Then Uninstalled the Module and Then Re installed - No Success
When I look at boutique Demo
http://www.joomla51.com/demo/0121/index.php
I can see that is the way I want my grid Gallery to be....
Totally Lost....
Can you throw you knowledge this way?
