Interesting. To be honest I have never had the opportunity to try this plugin on a site with only one or two pages of posts so perhaps it is a genuine bug that doesn't correct itself until it has enough 'pages' of posts to deal with.

I can't see any other reason to be honest. It simply relies upon WordPress variables to do it;s stuff so that must be it.

I am sorry about that but it looks like it may not work until you have a few more pages in place. Perhaps that was the problem with the other one as well.

When I next work on it I will see I can work out why.
