Get errors when installing:
Fatal error: Class 'Flow\Model\Header' not found in /var/www/wiki/extensions/Flow/FlowActions.php on line 37
It just cannot work at all...
I have tried to install it again in a new empty MediaWiki, but failed again.
Version: REL1_23-branch
Severity: critical
That's strange.
Flow.php:91:$wgAutoloadClasses['Flow\Model\Header'] = $dir . 'includes/Model/Header.php';
includes/Model/Header.php:3:namespace Flow\Model;
Those two lines should be enough for PHP to figure it out. Which version of PHP are you running? Namespaces were introduced in 5.3.0.
Flow development has required changes to core MediaWiki. Even the version of Flow that you're using from April required MediaWiki 1.24. Note the caution in https://www.mediawiki.org/wiki/Extension:Flow , it's a fast-moving project.

I am using PHP 5.3.10.
I confirm this problem is solved by updating MediaWiki to 1.23.6.
This problem is caused by bug #67440, which is fixed in 1.23.6.

When I update MediaWiki to 1.23.6, I successfully installed Flow plugin.
(Unluckly, it doesn't work well now. But that is another problem.)
