I realize this sounds like a duplicate card, but please READ ALL THE WAY THROUGH.
joey had mentioned "when I try to click on (the) card I get a "overlay" 50% black color screen and nothing happens". This only happens to me when I'm using the "Search and Filter Cards" option, AND when I click on the SPECIFIC card directly.

I've tried all of these in multiple browsers and the SPECIFIC card STILL won't open when using the "Search and Filter Cards" option.
