APC + Class 'Yii' not found problem


I’ve upgraded my Ubuntu that comes with PHP 5.3.2 instead of PHP 5.2.x, and since the upgrade if I turn APC extension on my Yii based (with some extensions) site wouldn’t work. Web3CMS, Yii Blog apps work fine with APC. I restarted Apache in order to clean APC cache, but the problem still exists.

Here’s the log snippet:

[Fri Jun 25 09:15:22 2010] [notice] caught SIGTERM, shutting down

[Fri Jun 25 09:15:23 2010] [notice] Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.2 with Suhosin-Patch configured – resuming normal operations

[Fri Jun 25 09:15:25 2010] [error] [client] PHP Fatal error: Class ‘Yii’ not found in /mnt/linmedia/www/test/indexy.php on line 14, referer: http://test/indexy.php

[Fri Jun 25 09:15:25 2010] [error] [client] PHP Stack trace:, referer: http://test/indexy.php

I use Yii 1.1.2, PHP 5.3.2-1ubuntu4.2 and APC 3.1.3p1

What could be the problem?

Maybe a bug in that APC version or some misconfiguration? Could you check the APC section in the output of phpinfo()?

Yes, it’s solved my problem! Thanks!

(apparently the apc config file was changed during the upgrade)
