Title: Plugin makes sitemaps inaccessible Last modified: August 25, 2022 --- # Plugin makes sitemaps inaccessible * [juliaatgravity](https://wordpress.org/support/users/juliaatgravity/) * (@juliaatgravity) * [3 years, 9 months ago](https://wordpress.org/support/topic/plugin-makes-sitemaps-inaccessible/) * Hello! First of all, thank you for your very useful plugin! It is very helpful, however, it makes my RankMath XML sitemap inaccessible, also to Google’s Search Console. When accessing the sitemap for my posts, for example, it produces this warning: * Warning: Attempt to read property “ID” on null in /path-to-my-installation/ wp-content/plugins/posts-by-tag/include/class-posts-by-tag-util.php on line 27
^ * It would be awesome if you had a solution for this. Thank you!
