The code has been refactored for better readability, modularity, and handling of potential errors. Changes include: Modular Methods: Introduced initializeTwig and checkMaintenanceMode for separating concerns. Improved Error Handling: Centralized error logging for clarity and consistency. Reduced Duplication: displayTemplate now handles the rendering logic to reduce redundancy in error page handling. Better Defaults: Default values for settings to handle missing database entries gracefully. Let me know if further refinements are needed!
