What recipe are you using and does it only crack when you move the cake? Please turn off the caps as it's hard to read and it is considered screaming.

If the icing is cracking when you move the cake, it is most likely lack of support. Make sure you have a heavy enough cake board to support the weight of the cake.

I agree with the above - what sort of board do you have it on? If there is not enough suppoirt, it will crack

Depending on what is causing the cracking, I've read somewhere on here that adding just a drop or two of vinegar while mixing the buttercream helps prevent cracking?? I'm not 100% sure on this, so I will see if I can find what I was reading.
