Redeclare of Error class in PHP7

[uaktags]

I seem to be getting an error that the Error class is already in use, so any of the validation functions seem to fail. This is apparently due to PHP7 as can be read in the manual https://secure.php.net/manual/en/class.error.php

Something to keep an eye on. We must rename our error class.

Change line 77 in Applications/core/My_Controller.php from:
$redirect_url = empty($this->mModule) ? 'error' : $this->mModule.'/error';
to
$redirect_url = empty($this->mModule) ? 'myerror' : $this->mModule.'/myerror';

Rename Applications/controllers/Error.php to Applications/controllers/Myerror.php

Rename the class in Applications/controllers/Myerror.php from "class Error" to "class Myerror"

Edit as needed. Don't use "myerror" -_-

Thanks for the issue. I will further check with this, and I would prefer rename it to something like "NotFound" instead.

Definitely:
Here's a solution, rename the error controller to syserr or "NotFound" as you suggested:
application/config/routes.php:

$route['error/']                         = 'syserr/';
