My Edit Entry page in the Control Panel is loading without the _add-ons or admin/theme/ascent folders, which seems to be causing my edit entry page to load incorrectly.

This started after updating to 1.9.0. I have updated to 1.9.1 and updated my server's PHP to v5.5+. Locally, these folders and the page load fine. On the server is where the issue comes in.

Any ideas why?
