redeclare class condition_info

I upgrade my moodle from 2.6.4 to 2.7.1. After upgrading I've got blank (white) screen. Then I turn on debug display in config.php

$CFG->debug = 32767;
$CFG->debugdisplay = true;

After that I receive an error: Fatal error: Cannot redeclare class condition_info in /home/moodle/public_html/lib/conditionlib.php on line 105.

Then I search and found that might be a problem with opcache (https://tracker.moodle.org/browse/MDL-45797). So I follow this doc - http://docs.moodle.org/27/en/admin/environment/php_setting/opcache.enable and enable opcache in php.ini:

[opcache]
opcache.enable = 1
opcache.memory_consumption = 128
opcache.max_accelerated_files = 4000
opcache.revalidate_freq = 60

; Required for Moodle
opcache.use_cwd = 1
opcache.validate_timestamps = 1
opcache.save_comments = 1
opcache.enable_file_override = 0

; If something does not work in Moodle
;opcache.revalidate_path = 1 ; May fix problems with include paths
;opcache.mmap_base = 0x20000000 ; (Windows only) fix OPcache crashes with event id 487

; Experimental for Moodle 2.6 and later
;opcache.fast_shutdown = 1
;opcache.enable_cli = 1 ; Speeds up CLI cron
;opcache.load_comments = 0 ; May lower memory use, might not be compatible with add-ons and other apps.

Reload apache and it still doesn't work. I also try to comment out part ; If something does not work in Moodle and error still occurs. Any idea what might be wrong?

I also read that might be a problem with themes. Before I upgrade I switch theme to Clean which is default theme in 2.7.

I have ubuntu 14.04 with PHP 5.5.9-1ubuntu4.3 (cli) (built: Jul 7 2014 16:36:58)

This might be a bug or an incompatibility with the opcache system.

  • i would suggest to turn the opcache off: opcache.enable = 0. The opcache is only good, if everything works and you want to gain some additional performance.
  • restart PHP
  • restart Apache

Finally try one of these downloads:

If the problem persists: please open a new bug report over at moodle and reference the report you found. it is clearly related.
