Upgrade seems to work - but the old version is still running

I've got composer running OK. It was a bit of a battle as I have to run it as a cronjob. Still it seems happy:

- Installing mediawiki/semantic-media-wiki (1.9.1.1) Downloading: connection... Downloading: 100% Extracting archive - Installing mediawiki/semantic-result-formats (1.9.0.1) Downloading: connection... Downloading: 100% Extracting archive Writing lock file Generating autoload files X-Powered-By: PHP/5.3.27 Content-type: text/html

However, when I got to to Special:Version

This is what it says:

Semantic MediaWiki (Version 1.8.0.5)

This is the run-string:

cd www/wiki;php -c etc extensions/Composer/bin/composer update --verbose ;php -c etc extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php -d 50 -v

If you use APC or opcache, you may need to clear the cache to see any MediaWiki configuration changes: restart Apache or php5-fpm or use the button on Special:APC (APC extension).
