Theme errors

I’m having some issues with Aegaeus and not sure where the problem comes from. It only appears with Aegaeus, and goes away when other themes are being used. I’ve turned off all plugins, and the issue still persists. I get error messages on my dashboard, and it prevents me from creating and uploading new content. Here is a screenshot of my dashboard with plugins turned off (no plugins), and here is screenshot with my plugins turned on (plugins)

I’ve even tried re-installing wordpress, and now not sure what to do.
