Case Study - Fixing Database Upload Errors on Real Estate Website

Project Overview

A client from the real estate industry approached me on Upwork with an urgent request. Their property management website, hosted on GoDaddy, had multiple databases for different property categories. The system worked perfectly three years ago but recently started failing whenever they tried uploading new properties.

The Problem / Challenge

The client was unable to upload new property records. Every attempt returned an error, even though older properties had uploaded successfully in the past. The key challenges were:

• Outdated core PHP codebase that hadn’t been maintained for years.
• Possible database schema mismatch and deprecated PHP/MySQL functions.
• Security risks due to unstructured and exposed PHP scripts.

This blocked the client from adding new listings to their live site, directly impacting their real estate business operations.

My Role & Tech Stack

I was hired as a PHP & MySQL developer to identify and resolve the upload issue.
Tools & Tech Used:

• Core PHP
• MySQL (database debugging & schema validation)
• GoDaddy Plesk hosting environment
• Upwork embedded Zoom (for real-time debugging with client)

Solution

Since the issue wasn’t reproducible on my local setup (uploads worked fine locally), I identified that the root cause lay in the server environment and file handling logic. To resolve this:

• Conducted a live Zoom debugging session with the client on their GoDaddy server.
• Fixed form handling & file upload logic so property data and images were processed correctly.
• Corrected missing includes and folder references in the admin panel code.
• Fixed upload directory’s permissions issue on Plesk server environment.
• Ensured uploaded images were stored in the correct folder and properly displayed on the frontend.

Impact / Results

The fix restored full functionality to the real estate website:

• Property uploads were successfully re-enabled, allowing the client to add hundreds of new listings.
• Identified critical security risks in the outdated PHP setup, giving the client clear guidance for future improvements.
• Helped the client save significant time and money by resolving the issue in a single Zoom session without requiring long-term redevelopment.

The client tested the solution live during the call and immediately confirmed that the issue was resolved.
