Hello,

Turning on debug logs, I found that there was a problem with https://plugins.trac.wordpress.org/browser/hide-categories-on-shop-page/trunk/wc-hide-categories-on-shop-page.php#L147.
As a matter of fact, $terms can contain a mix of WP_Term objects and numerci term_ids… So when it’s a numeric ID, it doesn’t have a ‘slug’ sub-object, so $term->slug is null.

So I had to change:

foreach ( $terms as $key => $term ) {
	if ( ! in_array( $term->slug, $data ) ) {
		$new_terms[] = $term;
	}
}

into:

foreach ( $terms as $key => $term ) {
	// Use get_term to get a WP_Term object from wether WP_Term object or term_id
	$termobj = get_term($term);
	if ( ! in_array( $termobj->slug, $data ) ) {
		$new_terms[] = $term;
	}
}

Maybe you’ll be interested to include that in your next version.

Hope it helps.

And thank you for your usefull plugin!
