Message wordpress: your site has a technical problem

Hello,

I get a notification from wordpress that there is a problem with your plugin. When I check the site I don’t see a problem right away, but I also received this email yesterday, so there does appear to be a problem.
Below are the error details.
An error of type E_ERROR was caused on line number 53 of the file

/data/sites/web/houseofhair-ranibe/www/wp-content/plugins/woo-variation-swatches/includes/class-woo-variation-swatches-product-page.php.
