Thread:Project:Support desk/fatal error message: SemanticMediaWiki

Hi Everyone,

I've installed mediawiki v1.22.0 and upgraded my old wiki mw-config and update.php. However when I load the wiki, I see this message:

Warning: Parameter 3 to addHTMLclass::hAddHtmlTag expected to be a reference, value given in /var/www/html/wiki/includes/parser/Parser.php on line 4020 Warning: Parameter 3 to addHTMLclass::hAddHtmlTag expected to be a reference, value given in /var/www/html/wiki/includes/parser/Parser.php on line 4020 Warning: Parameter 3 to parseFeed expected to be a reference, value given in /var/www/html/wiki/includes/parser/Parser.php on line 4020 Fatal error: Class 'SMWSQLStore3' not found in /var/www/html/wiki/extensions/SemanticMediaWiki/includes/SMW_GlobalFunctions.php on line 286

I don't think I'm missing an extension, so I'm not sure what it is referring to. Any help is greatly appreciated.

Thanks,

Roman
