I’ve followed the solution in this post… https://kriesi.at/support/topic/adding-links-to-a-gallery/?login_error
It works! But, it is only working when I “preview” the page. It is not working on the published page.
Why would it work in “preview” but not on the live page?
I found a solution. I think my issue was related to conflicts in the widget settings and the gallery settings.
