Why won't Google approve my sitemap? I'm using xml plugins!

Maybe something here? https://validator.w3.org/check?verbose=1&uri=http%3a%2f%2fwww.magniworkk.com%2f

Wow my sites a mess! Thanks for that link. So do I work on that by going to Appearance –> Editor –> and either css or php? If php is it the Main Index page or something else – do you know?

The good news is errors are cascading. So if you fix one sometimes several disappear. Most normally, errors occur where you have entered something – text, images, text into widgets, etc. The themes normally do not introduce errors nor does WP. So look to what you have entered.
