Cannot redeclare class

I'm getting the following error message in the Apache error log while running vBulletin 3.6.4.

PHP Fatal error:  Cannot redeclare class vb_datamanager_user
 in /home/path-removed/includes/class_dm_user.php on line 31, referer: http://domain-removed/showthread.php?t=13755

A snippet from class_dm_user.php looks like:

if (!class_exists('vB_DataManager'))

define('SALT_LENGTH', 3);

class vB_DataManager_User extends vB_DataManager # <- line #31

Also, it seems that class_dm_user.php is included somewhere conditionally as I even can not find any explicit reference to it (there are a number of class_dm_*.php files, obviously the required filename is generated on the fly).

Forgot to mention that I use the latest svn on Linux+Apache(mod_php).

comment:5 Changed 12 years ago by coredump

Sorry, forgot to mention that it's the latest version - php 5.2.0.

  • PHP Version set to 5.2.0

Unfortunately, Vbulletin is commercial software and we dont have licenses to add it into the stack of tested applications..

So, reproduce code is needed.

comment:8 Changed 12 years ago by judas_iscariote

ok, the fine folks at "Jelsoft" provided us a license in order to add this bulletin board to the test suite, however. Im unable to reproduce your problem, with php 5.2.2-dev + Xcache svn 1.2.1-dev + lighttpd

where should I click to get this error ?

  • Application set to vBulletin

I do not know why but now I'm unable to reproduce it either. I did not even upgrade anything (php, xcache, apache), just enabled xcache and restarted apache. However there were some significant modifications of the forum since than (few plugins installed, few uninstalled, some custom hacks, heavy style changes). Unfortunately now it is very difficult to restore it to the same state when this error message appeared.
I'll let it run with xcache enabled for a while and see if it will happen again.
