Title: Field 'extension' doesn't have a default value [Fixed in 4.0.51]
Post by: aikiroby on 17.02.2026 08:49:36
joomla 5... Upgrading Jdownloads component from version 4.0.48 to 4.0.50.

After that, I can't create no more categories, as the error: "the Field 'extension' doesn't have a default value".

I tried to downgrade to the previous version, but is not permitted.

Thank you in advance for your support.

SOLVED!
via phpMyAdmin, go to structure of the table 'jdownloads_categories', change 'extension' field default to NULL

Oh, that's an annoying bug, unfortunately. That shouldn't have happened. Sorry to all users.  ::)

I'll fix it right away and release a fixed version afterwards.

Unfortunately, this does not fix the problem.

The correct default value must be: com_jdownloads

However, this is only required when using the Joomla multilingual function. The fixed version 4.0.51 will be published in the next hour.
