Please help

Hello there!

Congrats for the plugin.

I installed it a few days and I have been struggling with one issue.
After installation, when I click on my menu items (which are categories for my posts).I either get Error 404 or i get directed to a post which has a name starting with the name of the category (i.e, category is “flights” and when clicking on “Flights” on my menu, instead of showing all the “Flights” posts i get redirected to a post called “Flights to Australia”.

How can I fix that?

And one more thing:
when i richg-click -> View Source
I should see something like !– Performance optimized by W3 Total Cache. Learn more: http://www.w3-edge.com/wordpress-plugins/

But I do not. How can I fix that?

Best,
Martin
