What exactly do you mean by “… when LYTE is not active”?Your plugin uses shortcode. When I deactivate it, all vids are completely gone, only some remeining code remembers visitors that something went wrong …What can explain to my client?

I have seen LYTE working on multiple site the last days/ weeks, including my own blog (e.g. [https://blog.futtta.be/2025/11/05/radiohead-2025-jukebox/](https://blog.futtta.be/2025/11/05/radiohead-2025-jukebox/)), so this is not necessarily a generic issue with LYTE? * to advance troubleshooting, I would have to know if the problem also arises with a normal youtube-embed or a WordPress oEmbedded YT. * As LYTE acts on shortcodes but also on YT-iframes (in the HTML) and on a YT-URL on a new line, so can you try changing the shortcode into e.g. [https://youtu.be/s-sMWH85E5g](https://youtu.be/s-sMWH85E5g)( so just that on one line) to see if that does or does not work? * Thread Starter [towpni](https://wordpress.org/support/users/towpni/) * (@towpni) * [6 months ago](https://wordpress.org/support/topic/error-153-2/#post-18713716) * Breaking news, it’s a hosting issue. I migrated the complete website to a staging site (different hoster) and voilà – videos (with your plugin activated) are looking good, no error 153. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 months ago](https://wordpress.org/support/topic/error-153-2/#post-18714107) * wow, how … weird. any difference in the HTTP response header tags that could explain this? * Thread Starter [towpni](https://wordpress.org/support/users/towpni/) * (@towpni) * [6 months ago](https://wordpress.org/support/topic/error-153-2/#post-18714682) * After deleting “Security Headers”, sun was shining again. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 months ago](https://wordpress.org/support/topic/error-153-2/#post-18714699) * great! 🙂 * [Sonnenschauer](https://wordpress.org/support/users/sonnenschauer/) * (@sonnenschauer) * [4 months, 4 weeks ago](https://wordpress.org/support/topic/error-153-2/#post-18756323) * I was also able to fix the error.

Had same Error 153 on a client website with WP YouTube Lyte embeds. Found that [Security Headers](https://wordpress.org/plugins/security-headers/) plugin is used there and `Referrer Policy` header was set to `same-origin`. Changed it to `strict-origin-when-cross-origin` and embeds plays fine again, no more Error 153.
