I need some help with this as it drives me mad.
Some blog posts have an external URL appended to them: https://www.my-site.com/blog-post/www.external-site.com
I get hundreds of such pages from one single external URL.
Any ideas what might be causing this? It is not happening with all external URLs. Just this one. I've even checked if it was added with the protocol (http://) in front and there aren't any such issues.
