I had the same problem and was following the fix too, but I made a copy of that file in my child theme under my-theme-name/buddypress/bp-members/screens/register.php. I didn’t want to change it in the original plugin file, but it’s not working. Is modifying the original plugin file ok? I’m not sure why my copied version in my child theme isn’t working??
snorklebum thanks for replying and sending me the link for the ticket. I could not figure out why it was happening as it had worked before. I will keep an eye on the ticket for updates.
