When migrating from MyBB to wpForo using the Go2wpForo tool, the assignment of categories to forums is incorrect. Although the posts are present in the database, they are not displayed. However, if the structure is adjusted to match the original MyBB forum, all posts are displayed correctly.

wpforo --> Forums -->Adjust the forum structure to match the MyBB structure. Note: Categories may be displayed as Forums and Forums as Categories.

On the same page, please press the following buttons one by one:

• Update Forums Statistic
• Update Topics Statistic
• Update User Statistic

Then delete the caches and check again. 

Next, review this FAQ to ensure your cache plugin (if any) is correctly configure: https://wpforo.com/community/faq/wpforo-and-cache-plugins/#post-37150

Important: Press CTRL+F5 (twice) on the frontend before checking. 

Please navigate to the Dashboard > Forums > Moderation admin page, press on the "Published" button, check if there are any topics. If you don't see any topics/posts, that means that the topics hadn't been migrated. If you see the topics/posts, go to Dashboard > Forums > Dashboard and press Rebuild Threads Button, delete all kinds of caches and check again.

I'm having trouble migrating from myBB to wpForo

There was no problem in the migration process (all the way to 100% without any glitch), and after that I can see the forum statistics (the new one) showing some numbers (more or less identical with the previous myBB), but when I open the new forum, all show 0 topics and 0 posts.

I went to Dashboard > wpForo > Moderations and clicked the "Published (####)" link and found that there are actually topics and posts. That means it's not an empty database, correct? So I assumed all the data were migrated successfully. I then went to Dashboard > Overview > Rebuild Threads. The notification said that thread rebuilding was a success, but nothing changed. All the forums still show 0 topics and 0 posts.

Is there something that I missed?
