Error fatal

Hi RamonJosegn,

Which version of WordPress are you running?

Line 46 is
Airbrake\EventHandler::start( $apiKey, $warrings, $options );

I am using WordPress 3.5.1.

This would be rather related to namespaces which were introduced in PHP 5.3.0. Check if your PHP version is the latest.

Thanks for support
