 * when i use the tag [fen] this error shows up, what should i do?
    Invalid FEN 
   string. A FEN string must contain exactly 6 space-separated fields.

 * Hi,
 * There is an example of use of the `[fen][/fen]` tag in your site admin, menu ‘
   Chess’ > ‘Memo’ > ‘FEN diagram’. Still, the recent versions of RPB Chessboard
   >= 6.0.0 include a chess diagram block editor (see in the page/post editor, block
   inserter > section ‘Media’ > ‘Chess diagram’), which replaces `[fen][/fen]` tags.
 * (please use the GitHub as much as possible instead of this forum for help requests,
