Heading Title tag:

A customer reported encountering a 404 error when trying to access the "Who's Online" page via the admin menu: Backend > Tools > Who's Online. The customer asked for guidance on how to repair this feature.

The osCommerce team promptly clarified that the "Who's Online" functionality had been moved to a free extension. It was removed from the core platform due to its limited usefulness and potential risks for high-traffic stores. In cases where there were 4,000-5,000 simultaneous users, this feature caused significant database load, leading to slow site performance.

To restore the feature, the customer was directed to download and install FREE extension from the official osCommerce marketplace: Who's Online Extension

By transitioning to the extension, users can safely re-enable the "Who's Online" functionality without compromising site performance, especially for high-traffic periods.
