So just before 'sitemap.xml', there is a space. When I try and copy the URL into web browser, it inserts %20 and I wind up with a page not found. When I remove the space, I can get to my sitemap. How to remove the space? Or is that not an issue for Google since it is probably just using a robot? Or is it because I am developing the site in a subdirectory?
I checked and I did not change it in _config.php. It's such an odd little issue, but at least it is working with a hard coded URL. I'll see if I can get to the bottom of it, I'm just learning about installing with Composer which is way cool so I am going to do yet another installation to see how that works and I will install the sitemaps module to see if I have the same issue. The site in question has some custom pages etc, nothing too fancy, but I am not ruling out that I goofed something up.
