I'm excited to use the Promotion Slider! Great work on this.
I'm pleased with this plugin so far accept for one issue. The promotion pages only work if I set permalinks to the default setting. Any other permalink structure causes a "not found" error. I upgraded to the most recent version and followed the installation instructions carefully.
/?p=123 - default, works
Desired custom structure: /%category%/%postname%/
"Sorry, the page your requested could not be found, or no longer exists."
The site is not live yet. Any help on this would be greatly appreciated. Thanks!
