You can switch to textual moves display from the wordpress admin page, settings menu, EmbedChessboard item, advanced settings section: enter “md=t” (without quotes) in the extended options textbox.
This would change the moves display for all chessboards. To change the feature for one chessboard only, you should add the “eo=t md=t” option to the pgn tag.
Not sure why would anyone want to switch to textual moves display, the figurine display is easier to read and it’s not language dependant. Please also note that, if you select the move text in figurine display, copy and paste in notepad, you automagically get the correct textual moves.
I’d be glad to hear what’s your driver for textual move display.
