Warning Column 'extension_id' cannot be null Package Install: There was an error installing an extension: com_listmanager.zip 15.04.2019 22:15

Hello,

I am running Joomla 3.9.1 with PHP 7.2.16 and get the above error message when trying to install LM 2.6.8_25_30.

I have also tried installing older versions of LM and the alternative methods (URL and Folder installations).

How can I get List Manager up and running again?

Hi,

That message sounds like the extension was not properly uninstalled/removed when you recovered the backup. You can try to remove manually remaining folders from the extension:
- administrator/com_listmanager
- modules/mod_listmanager
- components/com_listmanager

and try again the install package.
