Breaking: #79622 - Dropping thumbnail configuration for tt_content

See forge#79622


It is currently not possible to set the thumbnail field depending on the type of the record. Since tt_content uses different fields to store media we are removing this default configuration that was set to images by CSS Styled Content and assets by Fluid Styled Content.


Thumbnails in list view are no longer displayed for tt_content records.

Affected Installations

All instances.


To restore the configuration you need to set the thumbnail field manually to your preferred choice. You can do this by simply adding the configuration again in your Configuration/TCA/Overrides/tt_content.php file.

$GLOBALS['TCA']['tt_content']['ctrl']['thumbnail'] = 'image';
$GLOBALS['TCA']['tt_content']['ctrl']['thumbnail'] = 'assets';
