@engcom-November: out of curiosity, can you try to raise your max_input_vars value in the php configuration? See documentation: https://www.php.net/manual/en/info.configuration.php#ini.max-input-vars Its default value of 1000 might not be enough for the amount of fields you are trying to POST. This is just guessing based on a similar issue I saw some years ago around that form key error message.

@engcom-Bravo: what was the reason for closing this? Please always specify a reason when closing issues in the future, otherwise it's confusing the people who watch the ticket.
