问题
I have inherited a CI v2.0.2 project.
For development purposes, the project was moved to another subdomain, and the database.php file has been properly reconfigured.
The login page loads fine. However, after trying to login, I get an error from CI saying:
An Error Was Encountered
Unable to load the requested class: encrypt
In autoload.php, the database and session libraries are autoloaded. This file is the same as in the main codebase.
If I add the encrypt library in the above line, I’m unable to see the login page at all.
Below is the log file, from loading the login page -

The login works fine when used from the original domain.
Any pointers where I should begin looking?
回答1:
Presumably, the error is a result of one of the following reasons.
1) Somehow the filename of the library managed to chance causing CodeIgniter to be unable to find the file
2) Perhaps the file doesn't exist on the server and once again, CodeIgniter is unable to find it.
3) The filename may be different to that you are referring to in your code.
