All my logos have been uploaded and saved but Yoast Seo keeps the old theme logo in the preview view of the home page. I have already tried to deactivate the plugins and I only have one template installed.
If you clear your cache (server, plugin/theme, or CDN such as Cloudflare) does this resolve the issue? If you are not sure how to clear your server cache you should speak with your host provider.
If clearing the cache doesn’t resolve the issue, can you please provide the URL so we can check on what is being output in the page’s source code?
