MCreator Link Websites

So I recently became a proud owner of an Arduino, and of course I wanted to do some stuff with MCreator, so I went to the installation page for Link https://mcreator.net/download/link and I installed it, but when I went to look at the wiki sites, they all had an error message saying "The website encountered an unexpected error. Please try again later." I'm wondering if those websites had been terminated and don't do anything anymore or something like that. Thank you for your time :)
