At first I thought I wrote something in custom CSS that make my header title and subtitle vanish, but after browsing more I found out that pages/posts, that weren’t edited with page builder, had maintitle and subtitle show up. Just to be sure, I’ve tried disabling each plugins to find the culprit. Page builder was the cause. I need page builder to make the website smooth and responsive, but I also need both maintitle and subtitle visible. I’ve contacted Siteorigin support forums, but they couldn’t determine the solution and suggested to post here as well. Any advice is appreciated.
