Mediawiki PHP Fatal error: Cannot redeclare wfProfileIn() Error and Solution

Posted on in Categories , last updated December 26, 2011

I‘m running the Mediawiki software under Apache web server running on the Unix operating systems. I’m getting the following in my php error log:

PHP Fatal error: Cannot redeclare wfProfileIn() (previously declared in /var/www/html/wiki/includes/profiler/Profiler.php:14) in /var/www/html/wiki/includes/ProfilerStub.php on line 25.

How do I fix this problem under Mediawiki version 1.18.0?
