3.4.0.1 Test Environment Upgrade Errors

Describe the issue or problem
I am running an upgrade test from 3.3.0.6 to 3.4.0.1. During php upgrade check, it complained about my themes. I removed themes and left the default theme, and then the upgrade process.

Now the site won’t load, errors seem theme and plugin related.

Any advice would be great as I keep working on it.
