This code doesn’t replace {homepage} with the URL to home.
{exp:weblog:category_heading}
<a href="http://{homepage}">Home</a> | {category_name}
{/exp:weblog:category_heading}To narrow it down, this doesn’t work either:
{exp:weblog:category_heading}
<a href="http://{homepage}">Home</a>
{/exp:weblog:category_heading}The source simply renders as:
<a href="http://">Home</a>The site’s homepage is entered as index.php and the URL to the root of the site is http://www.example.com, in the preferences. We are running 1.6.
