You didn’t “disable and re-enable” your domain (there is no such functionality), you removed the initial domain from your account, and then added a new domain to your account.
The first domain name of your account is assigned to the directory htdocs, whereas any domain names added to the account later on will get their own directory, like example.com/htdocs. Which domain you add makes no difference, even if that domain was assigned to a different directory before.
To fix this, you can move your website from the htdocs folder to the <your domain>/htdocs folder.
