If you’re seeing a “breadcrumbs error” in WordPress, it’s likely due to one of two things:
- Your theme is not compatible with the latest version of WordPress.
- You have a plugin installed that is conflicting with the WordPress core code.
To fix the issue, first make sure you’re using a compatible theme. If you’re not sure, you can check the theme’s website or contact the theme developer for support.
Next, try deactivating all plugins one by one and see if that fixes the issue. If it does, then you know one of your plugins is the cause of the problem. You can either contact the plugin developer for support or delete the plugin and find an alternative.
