I upgraded to 0.9.3 by copying the update package over the instal (including all hidden files). Deleted the cache folders and ran grab clear-cache.
Now I get this error: Argument 1 passed to Grav\Plugin\ArchivesPlugin::onPageProcessed() must be an instance of Grav\Component\EventDispatcher\Event, instance of RocketTheme\Toolbox\Event\Event given
MAMP Pro, Yosemite. What do I need to look at to get going again?
