Page width locked

Somehow one of my projects have locked the width of the page, how do I reset the width to make the whole document. I have tried to reset the preferences, no success. Attached is a picture of the problem.

It looks like you’ve switched from wrap to editor mode to page view for that editor. See if you can select View > Page View > Hide Page View.

Preferences>Editor. In the middle of the window “Default Editor Width” This may be narrower that the width you are trying to drag it to.

Personally I use a narrow editor width. It helps me to write (fiction) in a width that is similar to that of a book page.

Thank you, it was indeed editor mode and problem solved.
