Field 'preview_filename' doesn't have a default... - [Cannot be reproduced]

[AGV]

When I want to store a new download the following message occur: Field 'preview_filename' doesn't have a default value

[Arno]

I cannot reproduce this with pre-beta 4.0.4.

Update from jDownloads 3.9 or new install with Joomla 4?
PHP 8?

Please could you send me pic from your phpmyadmin like this below?

Hi
Has there ever been a default Preview file name?

In Global settings you can delete 'Unused Preview Files from any deleted Download' and one can select 'View Preview File in Downloads List'

Hi, still the message:  Opslaan mislukt door de volgende fout: Field 'preview_filename' doesn't have a default value

Hi,
Even with further attempts I could not provoke or reproduce the error with version 4.0.5. Neither when creating in the backend nor in the frontend.

Perhaps it only occurs with certain combinations of settings.

It is noticeable that an older field definition can still be seen on the screen photo of the database. Please uninstall the old test version completely and install the latest 4.0.6. It will be released this evening. Then try again. If the error still exists, please send me the exported file with your settings.
