Thanks jzero, you did indeed point me in the right direction :)
I must confess that I had not tried searching the forum for 'Skip Navigation Links' before making my original post. With hindsight, that was a silly mistake. At the time, I thought the rendered code sample was unique to my site and my primary focus was on
finding out why I could not find any reference to it in my own code. I was unaware that it was a default setting of SkipLinkText within the asp:Menu control and thus not explicitly quoted in my code. I now appear to have resolved the problem by configuring
asp:Menu with a setting of SkipLinkText="".
However, I am still bewildered by why this problem suddenly popped up in 2020 for a website I created in 2008. The link you provided was dated 2006, so other people hit this problem before I even started to create this website! Two of my other websites have
also been similarly afflicted. one of which has never been updated since June 2019.
Perhaps ASP.NET is susceptible to infection by Covid-19...
