TYPO3 Exception 1294586442

Template is not writeable

Happens when your file permissions (Unix) are not correct if you include TypoScript from a file and try to edit it in the backend.

Solution: Change file permissions to make the file writeable by the webserver or move the file to a writable location. For example, if you need to make changes on TypoScript of an extension you should not do it in the extension directly but in your own template files.
