Hello,
I have try SEMrush tool to make a review of my site and I have an error in sitemap.xml url.
I have look the page, and all I can see to block the SEMrush bot and made an alert, is the url of the project.
Here is the html code:
module Drupal XML sitemap
It should be transform in a https link.
Just a minor bug, but anyway a bug ;)
