I've created a custom header using Elementor, and it looks perfect in the editor across all responsive modes (desktop, tablet, and mobile). However, when I publish the header and view it on different browsers and devices, it completely breaks. The menu collapses vertically, icons become huge, and the layout is distorted. I ensured that the responsive settings in Elementor are correctly configured. Cleared the cache in my browser and on the server (Hostinger). Checked for conflicts with plugins (I use PhastPress and Seraphinite Accelerator). Temporarily disabled caching plugins to see if they were causing the issue. Verified that WordPress, Elementor, and all plugins are updated to the latest versions.
