Layers button disabled, unable to move objects forward and back

[Delta5E2B]

I have a file that won't allow me to look at the layers within nor move objects forward and back. Does anyone know what's going on and how I can fix it? I've attached a photo for reference.

Hello, are the other layers locked? i know when I've locked a layer I can't move it within the layer stack. Also, it's not clear from the screenshot, but is there more than one layer?

I'm having the same issue. Also, when adding new elements(text, media, etc) new layers ar not added.
