More CSS Overriding issues! This time featuring more popup gallery!

For whatever reason, with the last update to the plugin, some background gradients and colors were added to my images??? Needless to say that was ugly and made my entire site look weird, so here’s the code to fix that:

.vp-portfolio__item-img::after {
    background-color:transparent!important;
}

.vp-portfolio__item-img::before {
    background-color:transparent!important;
}

The other problems I’m having are:

1. Can’t change the background color in the popup gallery from black to white as needed.
2. I want captions to show up while in the popup gallery, not on the main portfolio page, but that doesn’t seem to be an option either.

The page I need help with: [log in to see the link]
