Okay, now I started with a limit of 4000. In attachment defect-xml-sitemaps-settings.png you see a screenshot of this setting.
It produces three compressed sitemaps. But again, it does not work. See the attachment. Can I perhaps send you these sitemaps via email? If you can have look at it. Where is the problem?
Google says, the site
map sitemap1.xml.gz overwrites the maximum filesize. Is sitemap.xml.gz the container? Because Google shows this file too as not okay, the red cross.
