Wes, I have a similar issue. I have my slider in the SLIDER WIDE widget and then content in the SLIDER widget (could send you a screenshot if needed, but am using a proxy server so I can’t send a link). A thin gray line appears across the entire screen maybe ten pixels below the SLIDER WIDE widget right through the written content in the SLIDER widget. I think it’s associated with the top of the SLIDER widget in some way. Thanks for a heads-up on where to repair this.
I would need a link in order to know what’s going on. Screenshot/Code won’t be enough since I would need to inspect everything together. So just let me know once you have a link available and I can tell you exactly what needs to be done (it should be a quick fix).
Site is live, and the thin grey line is still there below the slider. I managed to move content below it with a line break and a header above it. Here’s the link: http://floridahikes.com . Look for it below “Welcome to Florida Hikes” and above our photo and Using the Map.
