Upgrade problem from aC 0.7.1

Hello together,

i have a problem upgrading from activeCollab 0.7.1 to ProjectPier latest release (aC works fine without any problems). I followed exactly the steps described in the manual, means:

I made a DB backup, overwrote my existing aC-installation with the ProjectPier files. I copied my original config.php into the /config folder.

After trying to start ProjectPier i receive this error message:

Caught Exception in AutoLoader: exception 'Exception' with message 'Could not find class file for "COMPANIES"' in /www/htdocs/v127770/projectpier/environment/classes/AutoLoader.class.php:105 Stack trace:

#7 /www/htdocs/v127770/projectpier/index.php(9): require('/www/htdocs/v12...')
#8 {main}

Her my config.php:

<?php
  define
('DB_ADAPTER', 'mysql');
 
define('DB_HOST', '*****');
 
define('DB_USER', '*****');
 
define('DB_PASS', '*****');
 
define('DB_NAME', '*****');
 
define('DB_PERSIST', true);
 
define('TABLE_PREFIX', 'ac_');
 
define('ROOT_URL', 'http://www.example.de/projectpier');
 
define('DEFAULT_LOCALIZATION', 'en_us');
 
define('DEBUG', false);
 
define('PRODUCT_VERSION', '0.8.0');
 
define('DB_CHARSET', 'utf8');
 
define('SHOW_MESSAGE_BODY', true);     
 
define('SHOW_COMMENT_BODY', true);     
 
define('SHOW_MILESTONE_BODY', true);     
 
define('TOKEN_COOKIE_NAME', '93c65403ce6b695a583e9e4c8c5b25e687283ee8');
  return
true;
?>

Any ideas?

Thanks for your help!

Try deleting the /cache/autoloader.php file - it is a cache file that is automatically generated.

Hello Ryan,

you mean /environment/classes/autoloader.class.php?

A /cache/autoloader.php isn´t existing, theres just a empty.txt in the directoty ...

Hello all together, no ideas?
