遇到Ion-auth / An uncaught Exception /无法找到您指定的模型

Question

I am using codeigniter 3.x and ion-auth 2x. Have a mini website going and I use github to manage the versions. The site works on my laptop but once I pull it to the ubuntu/apache webserver I get the below errors. I have checked that all files are there and they are. I have deleted the site and tried again - same result. I am stumped!

An uncaught Exception was encountered
Type: RuntimeException
Message: Unable to locate the model you have specified: Ion_auth_model
Filename: /var/www/example.com/public_html/system/core/Loader.php
Line Number: 344

Amazing. Two days I have been working on this. I changed the file name from ion_auth_model.php to Ion_auth_model.php and the error disappeared and the site is up.
