Thread:Project:Support desk/The directory used to store the settings, /usr/share/mediawiki1.7/serialized/, is not writable. Please make it writable by PHP to use this extension.

Hello ladies and gents,

I just upgraded my software suite to MediaWiki 1.16. My account has all the correct permissions. When I click Configure this Wiki, I get the above-mentioned error: The directory used to store the settings, /usr/share/mediawiki1.7/serialized/, is not writable. Please make it writable by PHP to use this extension. Perhaps there's an easy fix for this?

Thanks
