I got the same issue. But resuming it doesn’t solve the problem as @jeherve mentioned.
An error of type E_ERROR was caused in line 80 of the file /home3/theessk8/public_html/wp-content/plugins/jetpack/modules/calypsoify/class.jetpack-calypsoify.php. Error message: Uncaught Error: Class ‘A8C_WPCOM_Masterbar’ not found
Solution: I removed jetpack plugin. Then, installed Jetpack 9.1 manually. This solves my problem. Do not forget to turn off auto update for plugings.
