i use the generatepress theme. The gallery widget stopped working two days ago. Clicking an image just returns to the Home. I have deleted the widget from the side panel and recreated it. No resolution.
I wasn't aware that GeneratePress had this option. Are you sure that it's created using GeneratePress? It's most likely being generated by a page builder, and that case you might want to submit a support ticket to the page builder company that makes the page builder that you're using.
