WP Pagenavi WordPress plugin doesn’t work with the Top-Level-Cats plugin.

Top-Level-Cats wordpress plugin is great if you want your category sections to look like: www.mysite.com/recipes, rather than www.mysite.com/category/recipes; it simply removes the “category” subdirectory from your permalink structure.

WP Pagenavi is a great plugin that replaces the standard, “Previous Post” / “Next Post”, with a user-friendly numbered navigation system.

I discovered this plugin issue after I had Top-Level-Cats installed, then tried to install WP Pagenavi after it. The problem is that WP Pagenavi requires the “category” part (www.mysite.com/category/recipes) for it to work.

So after I disabled Top-Level-Cats from my wordpress plugins page, everything worked fine.

How about that? =)
