Thanks for the reply.

1.- Yes, in the wallet getnewaddress and the new address appears without problems.

2.- WordPress I already put it to see the debug, but since nothing new appeared, I removed it

I already have the son theme installed, but it does not let me copy and paste, in functions.php because this file already starts this way, and it throws me code error: <?php

There is some way to copy the code you gave me, not including the <?php, I’ve tried, but it throws me another error: {

Thanks for your help.
