What are your Season Folder Format and Specials Folder Format set to?

I guess the problem is my settings are corrupted. When I go to Settings > Media Management the page fails to load. I see the below error. Perhaps I can manually go into a setting file to update?

undefined is not an object (evaluating ‘s.specialsFolderFormat.errors’)
