Question
Install of Kunena damaged, can't uninstall via Joomla, how to manually remove?
I had just upgraded our site to J4 on a test server. Installed Kunena as a new install (never used before on the site). Seemed to work fine. Moved it to the primary hosting and didn't notice that their php was lower than the test server. Tried to use Kunena, got errors, realized the problem but like an idiot thought at first that it was just a bad install. I tried to uninstall Kunena (while still on php7.3) and now I can't remove it completely. The com_kunena component remains in the extension manager even after all other parts of Kunena are uninstalled. When trying to uninstall it I get:
Joomla\CMS\Filesystem\Folder::delete: Path is not a folder. Path: [ROOT]/administrator/components/com_kunena
Joomla\CMS\Filesystem\Folder::delete: Path is not a folder. Path: [ROOT]/api/components/com_kunena
Joomla\CMS\Filesystem\Folder::delete: Path is not a folder. Path: [ROOT]/components/com_kunena
Component Uninstall: Can't uninstall. Please remove manually.
I now have the site up at PHP8, but still cannot remove com_kunena and trying to install a fresh copy results in the error:
JInstaller: :Install: Error SQL Duplicate entry 'com_' for key 'PRIMARY'
Extension installation aborted.
Package Install: There was an error installing an extension: com_kunena_
How do I fix this or completely remove the old install so that I can try again?
I have the exact same issue! Please advise solution.
