Robots.txt Tester - syntax not understood

[JamesHancocks1]

I've looked in the robots.txt Tester and I can see 3 warnings:

There is a 'syntax not understood' warning for each of these.

XML Sitemaps:
https://www.pkeducation.co.uk/post-sitemap.xml
https://www.pkeducation.co.uk/sitemap_index.xml

How do I fix or reformat these to remove the warnings?

Many thanks in advance.
Jim

Hi James,

The right syntax is:

Sitemap: https://www.pkeducation.co.uk/post-sitemap.xml
Sitemap: https://www.pkeducation.co.uk/sitemap_index.xml

When you retry it should show up as working.

Martijn.

I'm to give that a go Martijn.

The text "XML Sitemaps" is in there and flagas as an error. Does this need to be reformatted as well or deleted?

Kind regards,
James.
