Fatal Error

When I go to search for an image in my Media Helper, I get a fatal wordpress error. It says the error is encountered with Yith Ajax Search Premium. I pasted part of the info below. I’m not sure though if it’s an issue with your plugin or theirs so reaching out here first. Thanks!

Howdy!

WordPress has a built-in feature that detects when a plugin or theme
causes a fatal error on your site, and notifies you with this
automated email.

In this case, WordPress caught an error with one of your plugins, YITH
WooCommerce Ajax Search Premium.
