Enable a domain's 4 subfolders' pages to show by using Temporary Url

Our site contains 4 subfolders, but each subfolder's pages display clearly only when domain registrar is referring to the site's domain names, and you check those pages on your browser, but not when we are trying to use temporary url to view the subfolder's pages. For example, contrast: (i) [login to view URL] versus (ii) http://serveripaddress/~account_username/subfolder1/[login to view URL] (i) shows successfully and conspicuously, but (ii) shows a lot of errors and warning messages on the page. Milestones to be created and released as each subfolder's problems is each solved. So 4 milestones separate top-ups and separate releases. This is the payment condition, so as to complete in phases. Total project fee/4 to be each phase's fee.
