sunshinephotocart on "[Plugin: Sunshine Photo Cart] Gallery will not open"

I'm able to create a gallery but it won't open. I've tried several variations (password protected and such) and no change. Any advice would be greatly appreciated!

In your WordPress admin, go to Settings > Permalinks and just hit save (don't change anything) then try again
