Upgrade error

[Janeric]

This morning I tried to upgrade to 4.4 and I kept on getting the same error, even after disabling the 3rd party customizations and restoring default theme.

Any suggestions? ( see attachment|

Make sure you are using a default unmodified theme for your AdminCP, and if you continue to experience problems I would recommend downloading the full zip from your client area, uploading that to your server, and manually visiting the upgrader.
