If you look at GSV - albeit 1 year ago - the road is replete with footway parking signs, none of which refer to markings and some which even face the wrong way. But above all, every marked area on the footway is a parking place with associated traffic signs(albeit they show the permitted sign for two wheels when the whole parking place in on the footway!), but then some have the 'end of footway parking' signs, but these aren't needed when the permission is not blanket but limited to parking places(for which a TMO would suffice, providing it was in sufficient detail).
It's a b****y mess.
But exactly how much of this bears upon the OP's situation?
OP, you live there so we need need up to date photos e.g. the parking place in which you were partly parked, the signs beyond and before of the form white on blue showing a car parked on a pavement - see the traffic sign in the parking place etc.
