Bug on wordpress site www.loveledger.co.uk + SEO implementation

A WordPress website is experiencing issues with one of its pages. On www.loveledger.co.uk, the 'View Files' page functions incorrectly when a demo PIN is entered. While the uploaded images display as intended, the main homepage Content is erroneously duplicated beneath them. The client seeks a freelancer to diagnose and resolve this bug. Specifically, when the PIN triggers the 'View Files' functionality, only the intended file gallery should render, without reproducing homepage elements below it. The goal is to have the 'View Files' page operate seamlessly to exhibit uploaded media solely, clear of any extraneous homepage duplication interfering with the envisioned user experience on that particular interior page. Diagnosis of the underlying issue and provision of a clean fix are required. Experience with WordPress development, debugging anomalies, and optimizing page functionality would serve the task well.

Effective SEO implementation is required.
