Question Posts missing after update 1.6

To test K 1.6 I updated a test site with K1.5.12

Upload in back end using J.1.5.20 installation manager without problem.
Install button appears and all install is ok
Back end working but front end is missing half of posts.

Downgrade to K1.5.12 and all posts are back again

Any ideas?

Thanks in advance,

Groenteman

Did you install a prior release of Kunena 1.6 on that test site?

The migration is only done once. If you go back to 1.5.x you need to make sure you remove any and all jos_kunena tables in order to force a new migration. Otherwise all posts made since the initial migration will apear missing.

Hope this helps!

You are right. I did an install of 1.6 alpha.
Just to see and roled that install back to a 1.5.12 again.

What about the content? Will it be erased too? What table should I save
and later load in the DB again?

Thank you for the reply,

Groenteman

The missing topics and posts come because of Kunena 1.6 beta only checks if you had installed K1.6 before. It's using jos_kunena tables instead of jos_fb, so it believes that forum was never downgraded back to K1.5 and keeps using the new tables which were created earlier instead copying data from K1.5.

I was going to add a way to detect this or at least give users choice to do the migration again, but I forgot to do it.

So the only way is to go into phpmyadmin (or similar tool) and delete all jos_kunena tables before going back to K1.6 after reinstalling K1.5. If you are using K1.5, deleting jos_kunena tables has no effect as they are only used in K1.6.. It just allows our version detection do to the migration again.

Thank you for your reply Matias.

This is what I did to downgrade. I deleted all the kunena tables in the database.
I uninstalled kunena and deleted also the left folder kunena in admin and components.
The fb tables are still in the db. I install kunena 1.5.12 with installation manager.

So 1.5.12 is installed and working. In components, kunena the icons show up
and the links work for the settings and so on. (front end is working too)

Now I try to install 1.6beta.

You are about to install Kunena 1.6.0-BETA1 (Beta Release). This release is not recommended to be used on live production sites. Installer is going to migrate Kunena 1.5.12 to Kunena 1.6.0-BETA1.

1. Prepare Installation
2. Extract Component
3. Install Plugins
4. Update Database
5. Finish Installation

In step 3 I get this message:
1: Migrate fb_version ... OK
1: Prepare Installation ... OK
2: Uncompressing admin.zip ... OK
2: Uncompressing site.zip ... OK
2: Uncompressing media.zip ... Failed The file '/***/administrator/components/com_kunena/archive/media.zip' could not be uncompressed

I can unzip that file manual without any problem.

What can I do to get 1.6b running?

If you have manually unzipped media.zip (into /media), please check that the directory and it's contents can be written by the web server. I believe that you have wrong directory permissions in there..

PS. you can also delete /media/kunena/ and make sure that media/ has the right permissions.
