Mittwoch layer menu error
Let me begin by saying that the Mittwoch theme is beautiful. Kudos to the designer(s) and supporter(s).
I just installed it on my wiki (v1.9.10.1). It all works well except the layer menus. Instead of the menus, I get this error message: "LayersMenu Error: setMenuStructureString: empty string." (see attached screenshot)
Any ideas?
