blank API REST page

Hi, I started the integration of MailerLite with Woocommerce.
I downloaded the plugin, filled in the MailerLite API Key, then followed the instructions as shown here: https://woocommerce.com/document/woocommerce-rest-api/ to create the Customer Key and Secret Customer Key.

It says you have to go to WooCommerce > Settings > Advanced > REST API

Then clic on Add Key and it says this takes you to the Key Details screen. Well, in my case, that part of the page starts loading the content, then stops but the content doesn’t appear. Instead, it goes blank.

I’m not a programmer and don’t know how to use nor have time right now to learn code, so, is there a way you’d try to fix this that doesn’t require using code? Do you know why it happens?

Thanks so much.

This is my website pilarretegui.es
I don’t know if the link below will let you in, because the problem is “backstage” and not to do with the aesthetic of my website
