A simple addition to functions.php does the trick.

See this Digging into WordPress article: Cool Things You can do with the WordPress “more” Tag. Skip down to the part “Stop more link from jumping to middle of page”

Try these links:

Could the problem be with your host’s server setup? Because “View Source” for the xml page looks funky.

In admin panel, go to SEO > Import & Export.
Check “Import from All-in-One SEO” and click Import button.

Very strange. I’m sorry, but I don’t have a clue :/

I just checked mine again. After selecting SEO > Edit files, robots.txt appears first, .htaccess appears second.

I see that you installed WordPress in the root so everything should work fine. Odd. Are you using the latest version of WordPress SEO?

It should be just below .htaccess
If you don’t see it, maybe you don’t have robots.txt in the root.

Your sitemap is located at https://www.goenviro.co.uk/sitemap_index.xml

Go into Google Webmaster tools and submit that URL as your sitemap. That’s the index file which points to the rest of your sitemap files. You only need to submit the one index file, not all the others.

What social share plugin are you using?

The URL for your sitemap should be https://mcdadi.com/sitemap_index.xml but I got an error when I visited it on your site.

robots.txt isn’t required BUT it is recommended.

I have a default one that I use on all my WordPress installations, shared below.

robots.txt

User-agent: *
Disallow: /cgi-bin/
Disallow: */wp-*
Disallow: *.php
Disallow: */feed*
Disallow: */trackback*
Allow: */wp-content/uploads*

Sitemap: https://yourdomain.com/sitemap_index.xml

Did you turn on OpenGraph metadata?
It’s found under SEO > Social.

Yes, you should install BUT you should also configure.
Let Yoast be your guide in this article on his website.

My suggestion: disable ALL other SEO plugins.

Running multiple SEO plugins is like running multiple antivirus programs. They’re all trying to do the same thing, inevitably leading to conflicts.

Personally, I replaced All-in-One SEO and Google XML Sitemaps (both good plugins) with Yoast’s WordPress SEO and have no regrets.
