Can you post images showing your results, and perhaps most importantly some screengrabs of the shadowcatcher settings and something of the scene set up? May just be me but I don't fully grasp what is happening for you from the description (also, you could submit a ticket and send in the scene, that way we can see everything directly :) )

Hi, as TomG already mentioned, please provide us with all the possible info to understand better the issue (you can also include the scene + all necessary assets so we can investigate further)
Regards.

ok, I try; I change the character, wich was very heavy in poly, by a box, but the problem is the same, so maybe you can see where I'm wrong!

This should be an easy fix. Set alpha mode to always solid. Instead of a legacy mat I have used a light material and enabled ''emit light''. That was added to the environment overrides. Ghosting be gone! ;) Hope that helps.

thank you for searching!!! but... I'm not too sure of the result: I mean, there is always the ghost plane; If I size it to cover all the ground, the frontiers desappear, but it's enlighting the part covered... I don't und'erstand, it was working fine, in precedent versions...?

Those lines you have marked on my image are the safety frames. As you can see in the final render, they aren't there nor is the ground plane. I'm adding my version of the scene here as well. Check it out if you'd like. I hope that helps! :)

thank you for your answers!
 in fact, something in the file was corrupting my render,  with the character; I rebuilt the scene, and it worked...
