The filter should stop it from creating another sitemap.xml. The sitemap has already been created though so that must be still showing.
Do you have anything else creating a sitemap? I’m asking as a sitemap is usually a good thing but you don’t want multiple sitemaps being generated and confusing things.
Anyway, In Dashboard –> Settings –> Reading at the bottom is a checkbox to discourage search engines from crawling your site. I was told that checkbox turns that off completely as it suppresses that output so…
This is just my best guess here but, would you check that, save the settings, then check to see if it’s gone?
I’d try that here but the only site I have 5.5 running on is a multisite where every site there has the ‘discourage’ option already set.
If that rids your site of the wp sitemap.xml then uncheck that again and check to see if it comes back. Check for it a few times over the next hour if you would. I want to make very sure cron doesn’t put it back later.
It would be very helpful if you would let me know either way that goes so we might help others with the same type problems or further pursue this if the file comes back.
