Thanks for the help, Will. I must be misunderstanding this in a fundamental way. Here's what I have in my layout:
<r:if_url matches="^/"> <r:snippet name="slider" /> <r:snippet name="main" /> <r:content part="sidebar" inherit="true" /> <r:snippet name="foot" /> </r:if_url> <r:unless_url matches="^/about$"> <r:snippet name="main" /> <r:content part="sidebar" inherit="true" /> <r:snippet name="foot" /> </r:unless_url> By my reckoning, that should render all the snippets -- including the slider, which has the About Me info -- on every page except the /about page, for which the above code is intended to remove the slider. But what happens in the above scenario is that the snippets are rendered twice on every page (This creates such a messy page that I have not even looked for the slider snippet to see if it is rendered twice. I think I should fix the reproduction first.) What am I missing?
