I made 2 cakes yesterday and covered them with fondant.
But the fondant started to melt a little bit Shall I put the cakes into fridge or it makes the fondant melt much more?
Not sure why your fondant is melting? Is it too heavy and falling off the cake? You can put fondant in the fridge, but I'm not sure if this will help your situation. If you do put it in the fridge, it needs to come to room temperature before it's cut.
Fondant ususally melts due high humidity or something under the fondant - acidic filling like raspberry, lemon.
If your fridge is dry ( no condensation runnign on the inside walls for ex) you can put it there.
as far as know it's not a good idea to put fondant in the fridge, but that's just from experience. the one time i tried doing that it got really sticky...
I always put my cakes in the fridge since we only use mousses and cream based fillings here. And have not have any problems with it. I make them on friday morning for example, leave them in the fridge until saturday afternoon and then deliver. And they are dry to the touch and look great
