Yes I also have the problem. It is a disaster.

HI, I have the same issue. I didn't see this post and have unfortunately opened a new one.

Best regards

Hello,

I don't know if it should be done in another way, but I managed to install Seblod 4, installing version 4.0.0 first and then 4.0.2. I hope someone else finds this useful. Greetings

Thanks for sharing this solution. It helped me get 4.0.3 installed on Joomla 4.3.1. I used pkg_seblod_4.0.0.Release.Preview.1b first (through multiple warnings), then installed the latest version straight over this. Glad to be able to get it working as I have a project that Seblod will be perfect for

For this then comes this!

Unknown column 'language' in 'field list' Paket Installieren: Bei der Installation der Erweiterung trat ein Fehler auf: com_cck.zip

Tests that also times one

Hello everyone, I’ve been facing the same issue while trying to install Seblod (pkg_seblod_4.0.2.Release.Preview.8) on Joomla! 4.2.8, getting the error message: 

JInstaller: :Install: Error SQL 42S22, 1054, Unknown column 'language' in 'field list'. 

After investigating, I manually added the missing columns in the table xxx_cck_core_fields, and it resolved the issue. Here’s what I did: 

1.) Added the language column: 

ALTER TABLE `xxx_cck_core_fields` ADD `language` VARCHAR(7) NOT NULL DEFAULT '*'; 

2.) Added the storage_filter column: 

ALTER TABLE `xxx_cck_core_fields` ADD `storage_filter` VARCHAR(255) DEFAULT NULL; 

3.)Added the storage_key column: 

ALTER TABLE `xxx_cck_core_fields` ADD `storage_key` VARCHAR(255) DEFAULT NULL; 

4.)Added the versionning column: 

ALTER TABLE `xxx_cck_core_fields` ADD `versionning` TINYINT(1) NOT NULL DEFAULT 0; 

After running these SQL commands, Seblod was successfully installed and worked properly. Hopefully, this helps anyone facing similar issues!
