As of Version 1.1.3 you can edit all settings in the new author panel of TYPEMILL. Just visit the url yourwebsite.com/tm/login and go to settings after the login. There you can edit:

All settings are stored in the \settings folder of TYPEMILL. It is not recommended to edit the settings manually, because it might crash the system if done wrong.

Advanced Settings

There are some settings that are not available via the author panel. Most of them are not really useful, but if you are a developer and if you develop a theme or a plugin locally, you probably want to display a detailed error report. To do so, simply add the following line to the settings.yaml:

displayErrorDetails: true

Don't forget to set it back to false before you deploy the website live. It is not secure to show the world your internal errors and many hosters will turn off all public error reports by default.
