Just to clarify, I haven’t used the Link URL under “Configure Items”, as there is not an option for the link to open in another tab or windows (the link is external to my site, so I don’t want to lose the traffic).
Instead, I have entered the link into the content editor, where the open in another tab is available. This is the link that doesn’t work.
I have the same problem. Created a gallery. When I roll over an image, the link text becomes visible and the mouse turns to a pointer, but the link is not clickable.
If I right click on the link and select “open in a new tab” it works.
