Ciarán ,

Hannah template
j51 grid gallery on home page
Joomla 3.7.3
svbnew.keithvb.com

I created a hidden menu with 2 items "link to facebook" * "subscribe to newsletter"
In grid gallery I added an image (image 5) and set the "Linked Menu Item" to "hidden >> link to facebook."
Clicking on image 5 I get a 404 error.
I've made the hidden menu visible on bottom left of home page so I can see that the menu item,"link to facebook" does function.

What have I missed?
I tried "http://www.joomla51.com/forum/8-commercial-templates/4432-renovate-mod-j51gridgallery-link-to-article#7605" but the link failed.

What next?

thanks,

Keith
