Parallax image problem

Doesn’t sound like you’re doing anything wrong but can’t really assist without more information. I’m thinking it’s either a theme, plugin, or server issue.

First try disabling the cherry lazy load / parallax plugins to see if it is coming from there.

Then try changing your theme to see if you have the same problem with media uploading.

Dont want to leave you with nothing so if you want you can try a temporary fix thorugh CSS, if your HTML is:

<div class="parallax-bg" data-parallax-type="image" data-img-url="https://academyofperformancearts.com/wp-content/uploads/2016/03/parallax-img-940x446-1.jpg" data-speed="1.5" data-invert="false" style="width: 1350px; margin-left: -675px; left: 50%;"><div class="parallax-img parallax-bg-inner" style="background-image: url(&quot;https://academyofperformancearts.com/wp-content/uploads/2016/03/parallax-img-940x446-1.jpg&quot;); width: 1417px; height: 672px; margin-top: 0px; margin-left: -33.5px; top: -111px;"></div></div>

or

<div class="parallax-img parallax-bg-inner" style="background-image: url(&quot;https://academyofperformancearts.com/wp-content/uploads/2016/03/parallax-img-940x446-1.jpg&quot;); width: 1417px; height: 672px; margin-top: 0px; margin-left: -33.5px; top: -111px;"></div>

Then you can change it by uploading your image of choice in your media library and then forcing it through css like:

.parallax-bg{
background-image: url(http://inserturlhere.com/pic.jpg) !important;
}

or

.parallax-img .parallax-bg-inner{
background-image: url(http://inserturlhere.com/pic.jpg) !important;
}

Hopefully it puts you in the right direction, if none of it helps then I suggest taking your query to http://www.getmotopress.com/forums/topic/ because it seems it might be coming from something they developed.
