Undefined property: wpdb::$woocommerce_termmeta

Hi!

Since a short time I’m getting Undefined property: wpdb::$woocommerce_termmeta errors on my shop pages. I’m trying to figure out what the problem is, but no luck so far.

Is there someone who can point me in the right direction, or has some advise on the issue?

This is the code that corresponding to the the error line:
/**
* Makes private properties readable for backward compatibility.
*
* @since 3.5.0
*
* @param string $name The private member to get, and optionally process
* @return mixed The private member
*/
public function __get( $name ) {
if ( ‘col_info’ === $name )
$this->load_col_info();

return $this->$name;
}

Thank you!
