I recently moved my application to a new AWS instance and discovered the code is tied to an older PHP build as well as an outdated CodeIgniter framework. The result is a blank site and multiple fatal errors. I need the entire stack brought up to date and the site fully operational again. Here is what I expect from you: • Audit the current repository, identify all PHP-version conflicts and deprecated functions. • Upgrade the framework to the latest stable release of CodeIgniter and refactor any breaking changes. • Align all code with a modern PHP 8.x environment and confirm compatibility. • Deploy the fixed application on my new AWS server (Amazon Linux 2, nginx) and make sure every public page loads without errors. • Provide a concise hand-off: updated source in Git, a list of changes made, and any server configuration tweaks. Acceptance will be based on the site loading correctly, major routes working as before, and no PHP warnings in the log. If you’ve handled legacy CodeIgniter migrations and AWS deployments before, this should be straightforward.
