CI update from 1.7 to 2.0 getting Fatal error: Class 'CI_Controller' not found in CodeIgniter.php on line 210

[eluser]tdegryse[/eluser]
I am trying to update CI 1.7 to CI 2.0 and followed the guideline for that (http://ellislab.com/codeigniter/user-gui...e_200.html), for some reason I keep getting following error: Fatal error: Class 'CI_Controller' not found in folders\system\core\CodeIgniter.php on line 210

I copied the website locally and I'm using Easyphp 12.1, the point of the whole thing is to update CI but also make some changes to the website. I really need to get started in the changes. If you need more info, please let me know.

Thanks in advance,
Toon

Sorry if this sounds stupid or just plain obvious, but did you replace the old "Controller" file with the new "CI_Contoller" file?

[eluser]tdegryse[/eluser]
I'm not sure if this is the wrong way but actually I installed the update and copied my files into the CI update. Then I adjusted the files in the application folder accordingly ..

[eluser]boltsabre[/eluser]
Hmmmmm... I cannot see it being a problem.

Can you remember if you (or anyone else) hacked your core files? I did an update 4 months ago and it took me all day because when I very first started with CI two years ago I changed one or 2 lines of code in one of the core files. Bam... update fail because I replaced my "hacked" file with the new "clean" file, thus breaking my application.

Or perhaps make a copy of your "old" site and try running the update the way they say and see if that makes a difference?

[eluser]tdegryse[/eluser]
I'm trying the old site on a new host, same version of php as the old one. I will let you know how it goes...

Is there a way to tell if the core files were touched or not besides opening all of them and comparing to a fresh download of CI 1.7?

Just delete the CI system directory and copy the new one over, then in your files
change Controller to CI_Controller, Model to CI_Moidel and make sure you copy
the new index.php file over. Replace all the application/config files.

Also It uses the new php Constructor.

Hey insiteFX,

In the old version the application folder is inside the system folder, should I copy my application folder into the root folder?

I have tried to take CI 2.0 and replace all the files in the applications folder with my own files. Then I changed all the constructors in my controllers. I changed the class extension to CI_Controller and CI_Model. After that I replaced the index file and the htaccess file. Am I missing something?

[eluser]InsiteFX[/eluser]
Yes, it should be like this for the new version of CodeIgniter.

Code:

application
system
index.php
assets
-- css
-- img
-- images
-- js
-- etc;

Thanks, now I have arranged all my files into this structure. I saw that the libraries in my project also extend Model .. I assume these have to change to CI_Model as well?

Any other changes I have to make so the program will find all the correct files on the correct locations?

@boltsabre: I've tried to upload the old website but then you talk about an update to do. Anyhow the old website is not showing, I assume because of a slightly different version of php.

Thanks a lot!

So I have started all over (again), copied my files separately into their new CI2 folders. I've adjusted the files after copying of course (constructor, extensions, etc)

Now I get two messages:
1. Fatal error: Call to undefined method CI_Security::SetLastPage() in ci\application\controllers\front.php on line 43
2. Message: mysql_escape_string(): This function is deprecated; use mysql_real_escape_string() instead. in mysql_driver.php

I know the second one is just deprecated but I keep this message for now, it gives me more energy than an empty screen does.

The fatal error, i'm curious if it's because I copied the security.php into the wrong folder? Or is there another reason?

Edit
I have new loaded MY_Security.php into appliation/libraries and my two message are gone. I'm stuck with the same message as when I started: Fatal error: Class 'CI_Controller' not found in CI\system\core\CodeIgniter.php on line 210


Thanks guys, any help is much appreciated!
