Shield with Oracle - get date format error

Thank you so much for your reply! It turns out that I was very confused because I had assumed I should be able to create a user by accessing the register path right out of the box. I'm an old-school developer, so I'm still getting used to the fact that the vendor directory can be like a hall of mirrors, and that there are routes can point to controllers, methods, and views, regardless of not being defined in config/routes,. The confusing thing is that right out of the box it's possible to bring up a login view by simply appending '/login' to the url, and you appear to be able to create a user by clicking the 'register' link there, but this is not how it's meant to be used. It's like trying to email your parents on the cardboard computer at the furniture store, only for some reason the cardboard computer actually powers on and lets you open gmail.

I subsequently understood that I can create users via the command line, which I have now done successfully, and that I need to build my application properly, in the 'app' directory, extending the built in classes, rather than trying to make use of the half baked application code that's crammed like yardgoods into the vendor folder. Maybe I'm just too old for this :-D

I think the moral of the story is that I should always ignore the vendor folder, like the dirty white van next to the school yard. Also, my first computer had a 20 megabyte hard drive, and my test app here is over 25 megabytes though I have not yet written a single line of code. I just have to stop fighting it. The world has moved on and I am getting old!

UPDATE: I will tell the agency I'm working for that I was being a dummy, that there's nothing wrong with CodeIgniter Shield, and they will have a good laugh at my expense. And I will tell them that I got a helpful reply from CodeIgniter support, so thanks again!
