This is commonly caused by caching plugins blocking JavaScript, or a conflict with other lightbox scripts.
If your video popup or lightbox isn’t working on your website, it’s usually due to JavaScript conflicts, incorrect video URLs, or plugin/theme issues. Below are the most common reasons and how to fix them:
🔍 1. JavaScript Conflicts
Multiple plugins or themes may load different popup or lightbox scripts, which can conflict and break functionality.
âś… Fix:
Check the browser console (F12 → Console) for errors.
Deactivate plugins one by one to identify the conflicting one.
Switch to a default theme to test if the theme is the issue.
🔍 2. Incorrect Video URL
Some popup plugins require the full, correct embed URL format. Shortened URLs like
youtu.beor wrong Vimeo links may not work.âś… Fix:
Use full YouTube link (e.g.,
https://www.youtube.com/watch?v=xyz)For Vimeo, use
https://player.vimeo.com/video/ID🔍 3. Missing Lightbox Script or CSS
If the lightbox library (like FancyBox, PrettyPhoto, or Magnific Popup) is not loaded properly, popups won’t work.
âś… Fix:
Ensure the necessary JS and CSS files are loading.
Check for plugin updates or reinstall the lightbox plugin.
If none of these solve the issue, try testing the popup on a clean WordPress install or staging site to debug further.
