Thread:Talk:Semantic Bundle/Upgrade to 1.22.1 make SMW give a fatal error on editing pages

I upgraded my wiki to mediawiki 1.22.1 and to the last semantic bundle (SemanticBundle-20140103.tgz) but when I edit a page text I'm getting this error.

Fatal error: Cannot access protected property WikiCategoryPage::$mPreparedEdit in /var/www/fountainpen.it/mediawiki/extensions/SemanticMediaWiki/includes/SMW_ParseData.php on line 477

I was getting the same error also after downgrading to previous version (SemanticBundle-20130929.tgz).

I'd to go back to 1.22.0, and 1.22.1 is a security release.
