I'm working on a WordPress site with Chinese language which use WP Bakery plugin.

I added woocommerce product category short code on home page to show some products from a category

It works on a all categories except one category.

when i add that category to show product it shows this error and products not showing

<b>Recoverable fatal error</b>:  Object of class WP_Error could not be converted to string in 
<b>/public_html/wp-includes/formatting.php</b> on line <b>3797</b><br />

Anyone know a solution or reason for this error please.

Thank You
