You have not created a legal board position for...

Hi

I am trying to "Play from set piece" to set up a position against a friend - who has not yet registered.

When I try to castle, I keep getting a message
"Illegal piece positioning for white king side castle
Illegal piece positioning for white queen side castle
Current Fen r1bqk1nr/pppp1ppp/2n5/2b1p3/2B1P3/5N2/PPPP1PPP/RNBQ2KR w KQkq - 0 1"

Can anyone please help?!

There are 4 'castling available' tickboxes. After you have moved the king and rook untick 'white king side' and 'white queen side'. The messages will disappear.
