Hi Rafasky, to investigate the issue I will need:
1. Live link to your site, or at least your theme (problems may arise because plugin doesn’t override styles of a particular theme).
2. Please try disable site plugins one by one (except AMO Team of course), maybe that’s not a theme but a plugin “conflict”.
But from what I see on your screenshot I could say that this problem, has answer in FAQ section, in this question – “What theme or plugins doesn’t work with AMO Team Showcase at the moment?”. I see no info panel on your screenshot. So that’s most probably MagnificPopup (JS library) conflict, there is no solution to this at the moment.
