WP Video Lightbox Plugin Troubleshooting

Q1 How do I use WP Video Lightbox plugin?

Solution 1 = Please view the following video to learn more.

Q2 How do I change the thumbnail size?

Solution 1 = By wpcommerce. You can customize the size of the thumbnail by editing the “wp-video-lightbox.css” file (it’s in the root directory of video lightbox plugin).

Q3 When I add some anchor text, only one word is displayed on the front page? How do I fix this issue?

Solution 1 = When you add the shortcode to your post or page, make sure you add the double quotes “”. For example anchor=”This is another test.”.

Responsive Settings

Q1 When I view the videos on my mobile device the image is too small. How can I fix this?

Solution 1 = Unfortunately the prettyPhoto library is not fully responsive in this plugin. If you need a better responsive option please take a look at our Lightbox Ultimate plugin:

Solution 2 = @terrymacsurfer in the support forum suggested the following code.

There’s no need to edit the js, just add width=100% to the HTML code of the src image and it is completely responsive.

Solution 3 = You can try changing the value in the code from the following file /js/jquery.prettyPhoto.js located inside the free plugin. Change the value from 200 to 40 as illustrated in the example below.

if((pp_containerWidth > windowWidth)){
	imageWidth = (windowWidth - 40);
	imageHeight = (height/width) * imageWidth;
}else if((pp_containerHeight > windowHeight)){
	imageHeight = (windowHeight - 40);
	imageWidth = (width/height) * imageHeight;
	fitting = true;

Solution 4 = Someone posted another solution in the following support forum.

  1. I have a problem, this page don’t have a transparent background when i clicked the video unlike this page

    The page is a template built in WordPress Page Builder, I don’t really know what is the exact problem since they have a same code.

    • Hi Daniel, I checked both links and I can see the videos but I am not sure what you mean by transparent background. Can you perhaps send me a screen capture from both sites pin pointing the problem you are experiencing via my contact form here.

      Thank you

  2. Good morning from Canada!
    I have added a Lightbox Video Gallery to my WP site and for some reason I have a couple of video links showing up on the very bottom of my homepage.

    • Hi Ken, I had a look at your sites homepage and I can’t see the links you mentioned. If you want, you can get in contact with me via my contact form. That will allow you to share a screen capture pointing to the links you mentioned.

      Thank you
