Everthing seems to be OK with your account. Are you still getting this error? I can try changing it for you if you want.

The error is still there bro

I finally could do it, for some reason when I go to "Edit signature" I have "No action" in default, so I just chose the option: "Enable my signature in all of my existing posts" and I don't get the error 403 forbidden.

I looked after the error and most people got it when trying to use different fonts or symbols in the signature, then I would need to ask my website provider to change the ErrorDocument thing, which I did, but I didn't get any answers yet.
Good that you managed to make it work, you just found a new  way to solve that problem I guess..
