Look at the message left down below by Shabook, one of the admins. There's link to Special:Preferences where you can switch to Source Mode as a default. Visual Mode editing isn't allowed here. An alternative is using the arrow next to "Edit", pressing "Classic Editor" and then pressing the "Source" tab to edit via Source Mode.
