This happens when loading the apps menu. The only categories that appear are Enabled and Not Enabled. It also seems to happen when trying to load the filetype icons. All folders are owned by web server user and I can’t find a reason the system shouldn’t be able to create a folder. Does this log message say what folder can’t be created?
