Thread:Extension talk:GoogleCustomWikiSearch/Failed opening required ...GoogleCustomWikiSearch.Settings.php

There is an error in the GoogleCustomWikiSearch.php file

You have " require_once $dir . 'GoogleCustomWikiSearch.Settings.php'; " but the file name in the package is actually, GoogleCustomWikiSearch.settings.php. You'll need to adjust one or the other or it will throw a fatal error.
