Hi Jason, thanks for trying to help me. No, I am not using a different template as default even though people can choose a custom template. But the problem occured with the default template. The file you mentioned already existed in the default template dir bit it contained common instead of default. Changing this resulted in a not working extended editor.

As far as I understood all new template files should have been copied into that default dir and being used, unless changed before. Then I need to apply manually, because GF protects the changes. But those new files did not exist before, so why does the file not exist by now ? Or do I get something wrong ?
