Hi
I am a simple user of wordpress, as millions
I just want to use a breadcrumb on my site
But I want to share with you a lot of fun, reading the “Installation” secion of your product. Just a simple sentence, but very funny :
6.Place <?php shopp( ‘catalog’,’breadcrumb’ ); ?> in your Shopp template file(s), if it is not present already.

whaourff ! Imagine the notice when you buy a new car : “to start the engine, just put the klimb into the nothernfilk and turn until klips.”

I can believe that more than 1% of people understand what you wrote. I don’t know what is a “template file”, and I don’t want to know. Why do you make the things so hard ?
