 * I’m getting the following in my error logs:
 *     ```wp-block-code
       PHP Warning: Undefined array key 1 in /homepages/9/d499301548/htdocs/clickandbuilds/WordPress/MyBlog/wp-content/plugins/google-sitemap-generator/class-googlesitemapgeneratorloader.php on line 827
       ```
   
 * Adding some diagnostics I see that it is trying to get the extension of:
 *     ```wp-block-code
       %61%75%74%68%6F%72%2D%73%69%74%65%6D%61%70%2E%78%6D%6C
       ```
   
 * which is URL-speak for author-sitemap.xml
 * App still seems to be working OK. FWIW we’ve opted to not include author pages
   in our site map.

 * Yes – I should have said – 4.1.19. I think the message was caused by that version.
