I get the error :
Deprecated: Non-static method BrowserHistoryLink::render() should not be called statically in L:\xammp7025\htdocs\mw1274\includes\parser\Parser.php on line 4278
Exception encountered, of type "Error" --------------------------------------------------
In the BrowserHistoryLink class the public function render($input, $args, $parser) must be 'public static function render($input, $args, $parser)...'
But after that still the Exception encountered, of type "Error" remains
