My CodeIgniter 4.5 app has started throwing 404 errors on routes that definitely exist, and it does so at random—sometimes the same URL resolves, other times it fails. I haven’t touched the route definitions or the .htaccess file, so whatever is wrong is lurking somewhere deeper in the framework configuration, caching, or server layer. I need a CI4 specialist who can: • Reproduce the intermittent 404 behaviour on a local or staging copy • Trace the failure point (RouteCollection, filters, caching, Nginx/Apache rewrite, etc.) • Supply a clear, permanent fix and document what was changed bid with "I am CodeIgniter expert and I will fix issue right away with $10" Thank you
