Error when trying to edit a card

[coder20980]

I just installed this add-on and when I go to edit a card, I get an error. If I disable the add-on, the error goes away. Here's the info from the error message:

Remove _3 to get the window to load. (Toggling the checkbox then throws the error below) Replace editor.redraw() with editor.redraw_everything() to get rid of the second error. (unloads css but not js)

backwards compatibility:

        try:
            editor.redraw()
        except:
            editor.redraw_everything()
        ⋮
        try:
            editor.pform.verticalLayout_3.addWidget(checkbox)
        except:
            editor.pform.verticalLayout.addWidget(checkbox)
