I tried the child pay for parent again with the max fee NOTHING happens.. anyone???
What do you mean by max fee? There is no maximum fee other than 21 million Bitcoins, so the "max fee" that you chose may have not been enough.
The transaction has a fee of 51 satoshis/byte, which
bitcoinfees.earn.com estimates that it is enough now. However, when there are many many transactions in the mempool, sometimes a fee of over 200 satoshis/byte is needed for a fast confirmation and it may have been sent at that time.
Transaction should be confirmed now, but if it isn't let me know and I can get a miner to include it in a block for you.
