I edited the default_question.php, but it has no effect. Dropped it to

components/com_communityanswers/views/question/
mytemplate/layouts/com_communityanswers
mytemplate/html/com_communityanswers

and at last I removed it completely. It has no effect.

I want to create a own layout for the default question view e.g. place author, categories, creation date in the footer panel. Please give me a hint which file I have to edit...

By the way, editing views/form/tmpl/edit.php and dropping it to my template overrides worked fine.

Best regards, Jürgen
