Thanks for the quick support. 🙂
OK I re-saved permalinks structure as well as cleared wordpress cache and sitemap-custom.xml is no longer throwing a 404 but am getting Missing XML tag error on Line 4 same as you when I test the custom sitemap in search console.
Hello,
I am having this same issue with a 404 on sitemap-custom.xml. The custom sitemap was not included in the sitemap index before and I did not intentionally want to add it. How did you manage to solve this?
Thank you in advance.
