Thread:Extension talk:RSS/Doesn't work on 1.18.3

The latest version does not seem to work in MW 1.18.3. (it works in 1.19) It throws this error "Fatal error: Call to protected method Parser::addTrackingCategory from context 'RSSParser' in ...extensions/RSS/RSSParser.php on line 356"

The version vor 1.18 works, but it has the "Error parsing XML for RSS" problem. Version 1.19 also.
