I'm facing the same problem as MagentoProblem this link. It is about messy frontend and backend of Magento 2. This happened after i set https://(My_Domain_Name).com into Configuration > Web > Base URLs & Base URLs (Secure) > Base URL for Static View Files & Secure Base URL for Static View Files.
I think the solution in the link will work for me but I don't have enough understanding on how to run the command CLI in Magento 2.3.1. I saw something about 'SSH', 'Terminal', 'Putty', but still not quite understand how to use them. Do i need to install any software or need to download anything else in order for me to run command CLI in Magento? I'm using GoDaddy Hosting > C-Panel > Magento 2.3.1 on Window 10.
