The sitemap can be read, but there are errors indicating disallowed URL,My website is built with WordPress, and the sitemap is automatically generated by the Yoast SEO plugin. Recently, the number of indexed pages has been continuously decreasing, so I decided to resubmit the sitemap. However, it shows the following error: 'The sitemap can be read, but there are errors indicating disallowed URLs.' Additionally, my page sitemap only contains 16 URLs, but Google Search Console shows that there are errors in 46 and 50 URLs. Also, Google is fetching a different website’s URLs as my sitemap, and my webpages are being identified as having automatic redirect issues. The report also shows that the canonical URLs claimed by the user are from someone else’s website, matching the URLs in the sitemap error. I’ve checked my sitemap, and it only contains my website’s URLs, and the page source code does not show any suspicious code. What could be the solution to this?
