When I search for Telerik stuff on google I get links in the form https://docs.telerik.com/devtools/winforms/api/html/m_telerik_underscore_delimited_path.htm, but you have updated your site, so the links should be in the form https://docs.telerik.com/devtools/winforms/api/telerik.dot.delimited.path.html. Even your internal search feature relies on Google search. They seem to be lazy about updating the links, or (more likely) there is something wrong on your side. You should fix it, so that Google becomes your friend again...
Even Wayback Machine is not aware of the changes...
