Hi Guys, If someone is still having problems importing data due to looped ‘Converting anonymous topic authors’ AND if you don’t need anonymous topic authors at all then I found a solution (in my case: bbPress 2.6.6 importing from PHPbb)

1) find this file: /wp-content/plugins/bbpress/includes/admin/classes/class-bbp-converter.php
2) TAKE A BACKUP
3) Replace the content of the file with this: https://pastebin.com/cRGQiLWs
4) Save and enjoy.

Please remember, this will ignore anonymous topic authors so only use this solution if you don’t need them.

I hope I could help. David
