After updating pro theme I can no longer access admin area - There has been a critical error on this website. Please check your site admin email inbox for instructions.
I renamed plugins folder but still see error, cleared cache, incognito mode, still no luck. It appears cornerstone is the culprit:
Fatal error: Uncaught Error: Call to undefined method ReflectionType::getName() in wp-content/themes/pro/cornerstone/includes/classes/Plugin.php:106
I have to restore a backup now to use the site but it can not be updated with these critical problems. What is the proper fix?
