Topics moved but where are the replys?
The Go2wpForo tool has already migrated thousands of WordPress plugins to wpForo. This is the first time I see see such problem report. I'm sure this is not the migration tool bug. Something is wrong wpForo installation or with the bbPress database.
First please make sure the replies are not migrated in database. Use phpMyAdmin Database manager of your Hosting Service cPanel and check the wp_wpforo_posts table. Let us know how many rows it contains and does it match to bbPress replies count?
In case you want to say thank you !)
We'd really appreciate and be thankful if you leave a good review on plugin page. This is the best way to say thank you to this project and support team.
