Solved Undefined property: stdClass::$rankId

Hello,

I get this error in KUNENA 6.3.10 when I look into kunena users in the backend:

       "Undefined property: stdClass::$rankId in ../libraries/vendor/joomla/database/src/DatabaseDriver.php on line 1309"

When I look into table kunena_ranks I can see an field rank_id but no field rankid.

The site was created as a new site, installing KUNENA and after that copying the content of the tables from the old site (runnung a very old Joomla 2.5) via SQL into the new tables. Mayby I did some error by copying because of the changes structure between the old and the new KUNENA-tables. Having a look into KUNENA_RANKS and into KUNENA_USERS I can't see an error.

Does anyone have any clues as to what could be the cause?

Regards,
Siegber

You did it wrong. First you should have imported the old Kunena 5.2 tables and only then installed Kunena 6.x (otherwise the database will not be updated).
Do the following:
1. create a backup of the new site
2. uninstall Kunena via the Joomla Installer
3. import the old Kunena 5.2 tables (are already available in your case)
4. install Kunena 6.x again
5. go to the Kunena Dashoard after the installation

it was a litle bit more complicated because of the very old Joomla 2.5:
- install a new copy of Joomla 3
- import the tables from Joomla 2.5
- install Kunena 5
- export the tables
- import the tables in Joomla 5
- install Kunena 6

So I told my brother-in-law next time not to wait 3 Joomla-versions before updating . I had a lot of work to help him.
