Reply To: Error 503 and Frequently bought together variation issue

Hello,

We suggest you try a different hosting provider. You can get trial periods for Cloudways or Kinsta hosting and check how your website will work there. They are better optimized for WordPress websites.

As for frequently bought together, it correctly adds variations to the cart specified in the bundle settings here https://gyazo.com/c4023779d076f3e18fcd0e60538c70a1
You need to check your variations IDs and add correct ones. Note that when you select a variation of the main product, your bundled products are not changed.

Kind Regards
