I'm new to Drupal community and I wonder if there is a solution to regenerate all urls from http to https?
I have already tried to just regenerate and try to update $base_url
in setting, nothing helped.
There is a setting in the XMLSitemap admin configuration that lets you set the base domain. Update that value, clear cache, and regenerate the sitemap.
$base_url
or the one in the admin configuration? If both are set to https, there is something else that is getting in the way then.
