It may depend on what you're trying to edit. For one of the main wiki pages, on the right side of the "Edit" button, there is a little down-pointing arrow. If you click on that arrow, you should see the editing option which is different from your default editor. Since I use the classic editor as the default, that little arrow lets me choose the visual editor. If you use the visual editor by default, the arrow should let you choose the classic editor.

You can choose your default editor in your profile, under "My Preferences". It's in the "Editing" section.
