qTranslate X plugin won't load default page

After I installed qTranslate X, all the web pages I can load and switch between Spanish and English. However, the main page, that I made as a default under Readings Settings, will not load the Spanish version. The page cannot be found. So, the main page is https://www.vinstonus.com. The Spanish equivalent is https://www.vinstonus.com/es but I also had a subdomain that I created for testing which was also https://www.vinstonus.com/es. So, I think I know why it’s not loading. I uninstalled WordPress from the subdomain. But now the Spanish version of the default page will not load at all now. Any ideas?
