Support has fixed it. There was an error with the theme. Thanks
Topic summary
Main issue: After updating to Dawn Theme 10.0.0, the storefront’s desktop and mobile menus appeared transparent. The poster found a workaround for desktop but the mobile menu remained transparent. An image was attached to illustrate the problem.
Requests for info: Responders asked for the store URL to diagnose; the poster shared livelaughsparkleboutique.com. A clarifying question asked what “transparent” specifically meant in this context.
Outcome: The issue was resolved by support, who identified it as a theme error. No user-side code changes or steps were shared.
Status: Resolved. No remaining action items in the thread. Key takeaway: The transparency was caused by a theme bug in Dawn 10.0.0, fixed by support; no documented workaround for others in the thread.
