slideshows in Breeze
Going in circles
A few questions:
• Are you sure the Slideshow category has Slides identified/assigned to it?
• Taking into account your previous post, something definitely sounds strange here: Are you accessing the page from a different URL than your WP settings?
For example: If you go to Settings → General and note the "WordPress Address (URL)" field, are you accessing the site at that exact URL (www/non-www is important as these are considered two different protocols).
If you'd like to PM me your wp-admin details, I'll be glad to login and take a look.
