Hi Dyfintie,
Here is what found for your error page issue

To address this GitHub issue about creating a custom error page, here’s a step-by-step approach:

1. Design the Custom Error Page:
    • Draft a unique design for the error page, incorporating brand elements, color schemes, and any additional information you want to provide (e.g., a navigation link back to the homepage, contact details, or a search bar).
    • Include a friendly message, like “Oops! This page doesn’t exist” or “404 - Page Not Found.”
    
2. Develop the HTML Structure:
    • Create an HTML file for the error page (e.g., 404.html or error.html).
    • Use semantic HTML and organize the page with headings, paragraph elements, and links for navigation.

3. Apply CSS Styling:
    • Style the error page to align with your website’s design. Consider using CSS to make the page visually engaging.
    • Add any animations or illustrations to improve user experience, if suitable.

4. Configure the Server to Display the Custom Error Page:
    • Update your server or hosting configuration to serve the custom error page whenever a 404 error occurs.
• For example:
    • In an Apache server, you can add the line ErrorDocument 404 /404.html to the .htaccess file.
    • In an Nginx server, you can set error_page 404 /404.html; in the configuration file.
5. Test the Custom Error Page:
    • Ensure the custom error page displays properly by navigating to a non-existent page on your website.
6. Document the Changes:
    • Update the GitHub issue with the progress, any decisions made, and a screenshot of the final error page for review.

This should address the issue raised in the GitHub repository. Let me know if you need help with any specific code or setup details.
