One more thing I noticed after the migration: Although all topic tags where imported, they are no longer linked to any topics. Not a big deal in my case but it’s good to know in advance.

+1 vote for an official export/import fix or dedicated tool 🙂

Searching the internet, I found https://github.com/pippinsplugins/bbPress-Export-and-Import

This plugin is designed to create an CSV export file per forum and allows you to import it to another forum.

1. Download the zip from github and install it like a regular plugin on both sites.

2. On the donor site, open a forum for editing and find the Export link on the right under Forum Attributes. Click it and you will receive the CSV file.

3. Go to the recipient site and create a new forum. Now on the right side under Forum Attributes (again) you’ll find the Choose File and Run Import buttons.

This does import topics and replies and on the front end, all seems to work well except for the number of posts per topic is too high. On the back end, Topics appear to be disassociated from the forum — it says (No Forum) — and the All Replies page turns up blank again.

Happily, heading over to Tools > Forums and running the top two “Recalculate…” and the “Count replies in each topic” options fixed things this time instead of making it worse 🙂

I really hope bbPress can be fixed to work with the normal WordPress Export/Import at some point but until then, the above steps should get you some good results.

Hi @treb0r23 – I just ran into the same issue. Wanting to move bbPress forums from one WordPress 4.0 to another 4.0 site, I tried WordPress’ own Tools > Export feature to create three export files, one with forums, one with topics and one with replies.

After importing them in the same order, it looked like everything was fine. All forums, topics and replies where imported successfully and seemed to be correctly assigned to their ‘parents’.

However, when visiting the front end, it turned out that only a two topics where visible in one forum. All other topics where missing and all other forums where empty. Replies where nowhere to be found either.

Even though topics and replies are marked as correctly associated in the back end, it does not appear to be the case at all.

I went to Tools > Forums to try to fix that. First, I tried “Recalculate the parent topic for each post” but even though it responds with “Recalculating the topic for each post … Complete!” after that, I can’t even open the All Replies list anymore. I get a blank page…

Then I tried “Recalculate the parent forum for each post” but this simply removes all evidence of association between all topics and their forum 🙁

This is just awful.

Hi donty, yes bbPress still works this way. As I’m using it only on the main site of a network so I can get around the issue by logging in as Super Admin when I need to manage the forums. But it does seem to make bbPress ill suited for true multisite use.

For multisite use, I can recommend https://premium.wpmudev.org/project/forums/?ref=RavanH-27681 wich is a much simpler sort of forum plugin but sometimes that is good 🙂

By the way, this is when editing from the WP admin back-end (via the Edit Topic link in the admin toolbar for example) not when editing inline on the forum page…
