Product bundle not shown (correctly)

Hi,

I want to use a plug-in called Product bundles. I have to versions available, one by Woocommerce, and a third party one.

When I install the one by Woocommerce all product pages go blank and it says:

2022/02/04 10:39:36 [error] 22385#22385: *4764299 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Call to a member function is_type() on null in /www/martingijzemijter_121/public/wp-content/plugins/woo-product-bundle/includes/class-woosb.php:2297

I tried a different one, and this one doesn’t give me an error, but it also doesn’t show anything of the product bundles on the page. When I switch to a default template, it does show.

What should I do?

Thanks!

Martin
