Thanks for that, it DID work if I was only showing excerpts (but if I was showing excerpts, the original ‘Continue Reading’ link would have worked also).
So the problem I have is that I want to show full posts 90% of the time. But some of them are really long, so I’m manually inserting a <!--more-->
tag in those posts, and it’s just for those exceptions that I need a ‘read more’ link to appear for the reader.
