Phoebus site will not let me update a theme

[Goodydino]

Phoebus: https://addons.palemoon.org/panel/ will not let me update my theme. I have tried everything I can think of and nothing works. It will not comply. It says the slug or the add-on file is not available. I tried five other browsers. None of them works. Maybe I need some kind of verification code? I have no idea where to find that.

Please try to include any relevant output from the Toolkit Error Console or the Developer Tools Web Console using the following procedure:

1) Clear any current output
2) Navigate or refresh the page in question
3) Copy and paste Errors or seemingly relevant Warnings into a single [ code ] block.
Web console:

Code: Select all

window.controllers is deprecated. Do not use it for UA detection.

I cannot select to copy anything from the error console. There is no way to do that.
