Header and Menu Troubleshooting
If your header is missing or your menu text is the wrong color, the cause is usually one of a few repeatable LT patterns. This guide helps you check them in the right order.
Typical symptoms include:
- the header seems invisible on posts, archives, or new pages
- the menu loads as black when you expected white, or white when you expected black
- the header blends into the nearby block influencing it
- mobile and desktop headers behave differently
Start with the easy checks
Before digging into templates or block settings, rule out caching and plugin conflicts so you know the issue is real and reproducible.
- Open the page in a private browser window.
- Clear any caching plugin and hard-refresh the page.
- If the Gutenberg plugin is active, temporarily deactivate it and test again.
- Check whether the issue affects one page only or many pages.
A single broken page often points to page-level block settings, while a site-wide issue usually points to template, plugin, or CSS behavior.
Fixing a header that is hard to see
When the header is present but the menu text blends into the background, the cause is almost always the Color Signal of the block next to the header. Adjusting that neighboring block is the fastest path to the right contrast.
In LT themes, the Header block is influenced by the first nearby visible block next to it. In practice, that is either the block placed right after the Header block inside the Header template, or the first block from the page content. When that nearby block has its Color Signal set to None, the menu can look wrong even though the header itself is working.
- Check the first visible block next to the header: either the block placed after the Header block in the Header template, or the first block from the page.
- Review that block’s Color Signal setting first, before spending time on background images or overlays.
- If the menu needs more contrast, change the nearby block’s Color Signal from None to Low or High, depending on the result you want.
- If you need a small workaround, place an empty Group block in that spot and use it only to influence the header Color Signal.
- Save and retest the page.

Restoring a missing header on posts and archives
When the header disappears on a specific content type, the template is the first place to look. A page can look fine while its archive or single-post template is missing the Header template part.
- Go to Appearance → Editor.
- Open the relevant template, such as Single, Page, Archive, Search, or a custom template you assigned manually.
- Confirm that the template includes the Header template part.
- If it does not, add it back and save.
This is especially worth checking on newly created pages, custom templates, and archive views.
