fullscreen image slider element caption frame background color

Hey dondela,
Sorry for the late reply, I took a look at your css and this is what is in your merged css:

.caption_framed .slideshow_caption .avia-caption-content p,.caption_framed .slideshow_caption .avia-caption-title,.avia-caption .avia-caption-content p,.avia-caption .avia-caption-title {
    background: #000;
    filter: alpha(opacity = 80);
    background: rgba(0,0,0,0.5);
    display: inline-block;
    margin: 0 0 1px 0;
    padding: 10px 15px
}

as you can see the background is black, while the css you posted above is white. Please check your custom css for this color or try adding this code in the WordPress > Customize > Additional CSS field:

.caption_framed .slideshow_caption .avia-caption-content p, .caption_framed .slideshow_caption .avia-caption-title, .avia-caption .avia-caption-content p, .avia-caption .avia-caption-title { background-color: rgba(255,255,255,0.80) !important;  }
.caption_framed .slideshow_caption .avia-caption-content p {
color: rgba(0,0,0,0.8) !important;  }

This will give you a white background, a red heading text, and a light black sub-heading text.

Please see the screenshot in Private Content area.
