What potential server settings in PHP.ini could cause login issues on a root server compared to shared webspace?

Potential server settings in PHP.ini that could cause login issues on a root server compared to shared webspace include session.save_path and session.cookie_domain. These settings may be configured differently on a root server, leading to session data not being saved or cookies not being set properly, causing login problems. To solve this issue, ensure that the session.save_path is set to a writable directory and the session.cookie_domain is correctly configured in the PHP.ini file on the root server. 

// Ensure session.save_path is set to a writable directory
session.save_path = "/path/to/writable/directory"

// Ensure session.cookie_domain is correctly configured
session.cookie_domain = ".example.com"
